John, I ran the query you supplied and it works fine for the actual miles driven. Units have a monthly mileage reading even if it is 0 (parked), but they do not always have a 12 month spread as vehicles are purchased throughout the year. For the last month and current I just need to show the odometer reading that is listed in the tblunitmonthmileage

Tiffany-
Try building the tblUnitMonthMiles table and then load it using the query I gave you. Are you saying that for some units the monthly mileage reading is skipped? In other words, for a given unit you might have a May and July reading, but no June? That complicates the miles traveled calculation that I do in the new query.
When you say you want Last Month and Current Month, do you want the mileage reading or the miles traveled?
And as far as getting the latest readings and an average, you'll use filters based on today's date to figure that out. Assuming "current" month is the last month for which there is an end-of-month mileage reading, you would do:
WHERE YearMonth = Format(DateAdd("m", -1, Date()), "yyyymm")
To get the month before that, use Format(DateAdd("m", -2, Date()), "yyyymm")

John,
Okay, so I need to delete the Last Month, Current and total fields from the "Assets" table? But leave those fields on Reed's Report. Then add tblunitmonthmileage to the Assets query. From there I need to tell the query to.....
What I need the query to do is show the Last Month - Current = Total, and average the last twelve months to get a monthly average usage. One problem is not all the unit has 12 months of history. And another problem is how does the query know what the Last month and Current month actually is? I have imported all the mileage I have archived into tblunitmonthmileage. and the structure is Unit#, YearMonth, Mileage.
Here is my Assets Query:
SELECT Assets.Unit, Assets.[Last Month], Assets.Current, Assets.CO, Assets.[Acc Code], Assets.[Well No], Assets.Model, Assets.Year, Assets.Description, Assets.Driver, Assets.[Mobile Phone], Assets.Department, Assets.[Vin#], Assets.License, Assets.Acquired, Assets.Weight, Assets.Supervisor, Assets.Images, Assets.Retired, Assets.Total, Assets.Sold, Assets.Notes
FROM Assets INNER JOIN tblunitmonthmileage ON Assets.Unit = tblunitmonthmileage.[Unit#]
WHERE (((Assets.Sold)=False));

Since LastMonth and Current will be constantly changing, those are calculated fields that should never be stored in a table. If you have loaded the most recent data into tblUnitMonthMileage, you can always find out the reading for the current month by joining Assets to tblUnitMonthMileage and filtering for the latest month. You can use the query I gave you to calculate the miles traveled each month.

Hi John,
I think I need to go back a few steps, let's tackle this from a step to next step perspective.
In my "Assets" table I have two fields, Last month and Current. I would like to tell those fields to get the data from my tblunitmonthmileage. Can I do link two tables this way? If so, How do I do this? The rows in tblunitmonthmileage are Unit#,YearMonth (yyyymm), Mileage. How does it determine what Last Month and Current is?

Query to calculate mileage:
SELECT T1.[Unit#], T1.YearMonth, T1.Mileage - NZ(T2.Mileage, 0) As Miles
FROM tblUnitMonthMileage As T1 LEFT JOIN
tblUnitMonthMileage As T2
ON T1.[Unit#] = T2.[Unit#]
AND T2.YearMonth = IIf(Right(T1.YearMonth, 2) = "01", Format(CInt(Left(T1.YearMonth, 4)) - 1, "0000") & "12", Left(T1.YearMonth, 4) & Format(CInt(Right(T1.YearMonth, 2)) - 1, "00"))
Explanation:
tblUnitMonthMileage has mileage readings for the end of each month. The YearMonth is stored as YYYYMM - I assume this is correct. This query joins two copies of tblUnitMonthMileage with a match on Unit# and a match on the *previous* month. The complex IIf is doing this:
If the month in the first copy is 01, look for a match in the second copy on (year - 1) and the value 12. For example, if YearMonth = "201101", it looks to match on "201012" - subtracting 1 from the year part and looking for December.
If the month in the first copy is NOT 01, look for a match using the current year and the month - 1. For example, if the YearMonth = "201109", it looks to match on "201108" - using the current year and subtracting 1 from the month part.
This should end up with rows for a given unit matching like this:
T1.YearMonth T2.YearMonth T1.Mileage T2.Mileage
201101 201012 3,420 1,500
201102 201101 4,500 3,420
201103 201102 6,000 4,500
... etc.
Subtract T2.Mileage from T1.Mileage to get the miles driven for T1.YearMonth.
Got it?
If that works for you, you can use that query as the source for an Append or Make Table query to build tblUnitMonthMiles that has the distance driven each month, not the mileage reading.

What is the SQL of Assets Query? What is the structure of the Assets table? It sounds like you need another table called perhaps tblUnitMonthMiles - Unit#, YearMonth, Miles - calculated from the data stored in tblUnitMonthMileage. What is the mileage reading in tblUnitMonthMileage? The odomoter at the beginning of the month, end of the month, or some random reading date within the month?

John,
Sorry... Reed's Report is currently getting all the data from the "Assets Query" this query is linked to my "Assets" table. I need to show on Reed's Report a monthly average using the last 12 months mileage but the info to get it from is on the "tblunitmonthmileage". The Unit# is the key between these tables. The structure for "tblunitmonthmileage" is unit#, YearMonth, Mileage.
Now, the "Assets" table has the Last Month-Current=Total fields and these are on "Reed's Report" but they are not pulling the data from anywhere, they are there because I have been hand entering them every month. But, I would like it if those fields were linked to the "tblunitmonthmileage" somehow because that would save me alot of work. As I said before, you showed me a way to append that data (mileage) every month and it gets appened into the "tblunitmonthmileage".

I need to show the monthly mileage on an existing report (Reed's Report) and an average for the year per unit. The unit# is already showing on "Reed's Report" and he has "last Month" & "Current" showing on his report, this info is actually coming from another table. I would like to replace "Last Month" with the Yearly Average. Could you guide me through this please?

Glad to hear you've made good progress. I don't think your new table duplicates data. The one I had you build merely contains the raw data - the Unit, Month, and the Mileage reading. Your new table sounds like you created it from a query that calculates the mileage driven. Miles driven during a month isn't the same as the mileage reading, so it's not duplicate data.

Hi John,
Well I have compiled all the mileages from the year by unit by month, in the format you suggested in a table. Now I need to show the monthly mileage on an existing report and an average for the year per unit. The unit is already showing on "Reed's Report" and he has "last Month" & "Current" showing on his report, this info is actually coming from another table. I would like to replace "Last Month" with the Yearly Average.
I believe you have told me not to duplicate data in tables. But, I have done just that. My Assets table has two fields "last Month" - "Current" = Total and my new tblunitmonthmileage that we created together has the mileage listed as monthly per unit. Is this a problem? And I have a form that that has these LM & Current in it so I can add them in every month. But, you showed me an easier way unbeknowst to you. Due to the table you had me make I no longer have to hand enter all the mileage every month I can now append it and it takes just minutes as to opposed to an hour. Thank you!
Tiffany

1) Open the table in Design view.
2) Click in the Primary Key field and de-select the Primary Key button on the
toolbar (2003 and earlier) or on the Design tab (2007 and later).
3) Hold down the Shift key and click YearMonth - that should highlight both
Unit# and YearMonth.
4) Click the Primary Key button.
5) Save
You'll probably need to delete all existing rows in your table before you do
this, then rerun your append queries after.

<sigh> I'm trying to get you to normalize the data. You say you have 10
spreadsheets. Is each one for a specific month? For the current year? First,
build a table that looks like this:
tblUnitMonthMileage
Unit# (whatever data type is suitable) First field in the Primary Key
YearMonth Text(6) (This will contain YYYYMM) Second field in the Primary Key
Mileage - a Number data type. Double if they record mileage in tenths; otherwise
Long Integer
Let's say your first spreadsheet is name "January". Import that as a table, then
run this query:
INSERT INTO tblUnitMonthMileage ([Unit#], YearMonth, Mileage)
SELECT [Unit#], "201101" As YearMonth, Current
FROM January;
That will load all the January data into your table and generate the correct
year and month. Do the same for each of the other 9 months, changing the literal
"201101" as appropriate. ("2011102" for February, "201103" for March, etc.)

None of my fields in my table have the name "month", they are named Unit,

In the 10 spreadsheets I have a column "Unit" and "Current", the months are not

Every month we added a couple of new units, so no monthly spreadsheet is the

That shouldn't be necessary. I gave you the table design below. But you should
avoid a field name Month because that's also a function. Use YearMonth instead.
If you import spreadsheet data that has the months across, you can load your
table with a series of Append queries:
INSERT INTO tblMonthMileage ([Unit#], YearMonth, Reading)
SELECT [Unit#], "201101" As YearMonth, [Jan]
FROM ExcelTable;
Run that query 12 times - once for each month.

What is in Jan-Dec? A number? Is it a mileage reading? Your table should look
like:
Unit#
Month (as in YYYYMM)
Reading
Running columns across that should be individual rows is a relational database

I have created a table and I need to populate the data from multiple
spreadsheets.
The table has 13 columns Unit# & Jan-Dec. Over the course of the year we have
added units, so every month the spreadsheet has changed and columns have been
added or deleted as well.
I do not need all the information from the spreadsheets, just the "unit" column
and the "Current" column imported into my database.
Is there an easy way to pull all this information into one spreadsheet and keep
it constrained to the unit number?
