Re: [MS_AccessPros] Not getting correct values on form with different inputs

 

Khalid,

If the fields and variables are numeric, don't use string functions on them. You need to explain what you are attempting to accomplish with:

Left([InvoiceRateLong], 4)

Left([InvoiceRate], 4) * TotalProductQty

Duane,

Yes the all fields in question are numeric.

Khalid,

The issue that stands out to me is you are using a string function Left() on a numeric value. I expect you should be using numeric functions to return parts of the number.

Hi John,

I have a Form “Export Invoice And Packing List” having only one Unbound control “ConsignmentNo” . Its Record Source SQL is:

SELECT DISTINCT PrepareInvoiceAndPackingListQuery.ConsignmentNo

FROM PrepareInvoiceAndPackingListQuery

ORDER BY PrepareInvoiceAndPackingListQuery.ConsignmentNo DESC;

On the sub form “Export Invoice And Packing List subform” data is entered, its Record Source SQL is:

SELECT [Invoice Values PakCaspian Ammended].*, Products.CustomValue

FROM Products INNER JOIN [Invoice Values PakCaspian Ammended] ON Products.ProductID = [Invoice Values PakCaspian Ammended].ProductID;

On Txt Box “TotalNetWt” After Update is:

Private Sub TotalNetWt_AfterUpdate()

       InvoiceRateLong = TotalNetWt * ValueOfCustom / TotalProductQty ç(This is hidden field)

       InvoiceRate = Left([InvoiceRateLong], 4)

'       TotalValue = (InvoiceRate) * TotalProductQty

       TotalValue = Left([InvoiceRate], 4) * TotalProductQty

End Sub

The issue and problem which I am facing is that if “TotalProductQty” is smaller or may be upto 40,000 thousands figure I get correct “Invoice Rate” and “TotalValue”. But if it is higher value like 7,700 I get wrong result. Take an example:

Total Cartons	Total Product Qty	Custom Value	Total Gross Weight	Total Net Weight	Invoice Rate	Total Value
50	40,000	4.00	105	102	0.01	400
500	7,700	1.10	500	492	7.02	54,054

 

In we check first entry on calculator 102 * 4 / 40,000 = 0.0102 (Invoice Rate) and we are displaying 2 decimals,  and TotalValue on our form is calculated by InvoiceRate 0.01 * TotalProductQty 40,000 = 400

Now in 2^nd entry if we check on calculator TotalNetWt 492 * ValueOfCustom 1.10 = 0.0702857142857143, We need to get here on our form InvoiceRate = 0.07 instead of 7.02

I cannot figure out where I am wrong, wether my update event is wrong or defined field size wrong.

TotalProductQtyàDoubleàStandardà0

TotalGrossWtàDoubleàStandardà0

TotalNetWtàDoubleàStandardà0

InvoiceRateLongàDoubleàStandardà2

InvoiceRateàDoubleàStandardà2

TotalValueàDoubleàStandardà2

Help required please.

Regards,

Khalid
