Re: [MS_AccessPros] Invoice totals

Ah, an oldie but goodie!

Bill Minnesota-

The technique is to use a Continuous form for the subform. It can have a default view of Datasheet if you prefer that look. In the form's footer put a text box with a control source:

=Sum([itmQty] * [itmPrice])

Then on the outer form put a text box that has a control source of:

=Forms!f_invoiceCreation![name of subform control].Form![name of the above text box]

No need to refresh at all in that case!

Bill, The old Northwind (2003 version) Orders form has a subform with a hidden total text box and the main form has a text box that has that hidden control as its ControlSource.

If your main form is not updating it might be due to a bug in Access 2010. Hot fix is at http://support.microsoft.com/kb/2899528

John,

I knew that. What was I thinking? I am a Knucklehead.

Now the field works on the initial calculation when I open to the record the first time. I can't seem to get it to repaint as I update the sub form.

On my subform ( sf_InvoiceItems) I have a field called ItmQty . I would like the field we have been working on (IncSubTotal on the form f_InvoiceCreation) to update each time I exit the ItmQty field.

I attempted to put a macro in. No luck. I attempted some code and it bombed.

I tried this as well as a few other things. DoCmd.Requery (Forms![f_InvoiceCreation]![IncSubTotal])

I am not sure if the Requery method is the correct way to do this since the field is not based on a query.

What do you suggest to get that field to repaint?

Thanks

Bill

Bill-

NEVER NEVER NEVER store the result of a calculation in a table. If you're intending to store this in the invoice table, the value will be wrong as soon as anything changes in t_invoiceitems. Just re-calculate it when you need it.

John,

This worked. See below. Yea.

DSum("[ItmQty] * [ItmPrice]","t_InvoiceItems","ItmIncID=[Forms]![f_InvoiceCreation]![IncIncID]")

Now that I have the field calculating I just have to figure out how to get it to fill the proper field on the table.

Since I put this in Control Source I do not think the value is getting back to my field IncSubTotal.

I will see what I can do. I am thinking a hidden field tied to the table/query which is equal to the field above.

Thanks,

Bill

Bill-

That has to go in the Control Source. Yes, it has to be refreshed whenever something changes in the subform - that's why I originally recommended using the AfterUpdate and AfterDelConfirm events of the form inside the subform.

John,

Am I correct in assuming that this will not have be repainted each time the sub form is updated? I read the post from Adam and you mentioned repainting. I would rather figure out how to do it so that is just automatically updates if the sub form is changed.

This is what I came up—

= DSum("[ItmQty] * [ItmPrice]", "t_InvoiceItems", "ItmIncID = " & [IncIncID])

Where ItmIncID is the field on the table t_InvoiceItems and IncIncID is the field on the form.

I tried to put it in the default value of the field on the form. That must be wrong because it was not accepted. I received an error "The expression you entered has an invalid string"

Either it does not go in Default value or I have done something wrong.

On the outer form, put a text box named txtTotal with a Control Source something like:

= DSum("[ItmQty] * [ItmPrice]", "t_InvoiceItems", "ItmIncID = " & [IncIncID])

=DSum("[Qty] * [Price]", "tblInvoiceItems", "InvoiceID = " & [InvoiceID])

In the AfterUpdate and AfterDelConfirm events of the form in the subform control put this:

Me.Parent.txtTotal.Recalc

I am attempting to put together an invoice. The invoice will be the main form. The items, including the price, will be on a continuous sub form.

I would like invoice to calculate the total and taxes automatically. However I am having a hard time figuring out how to get the total from a the sub form to transfer on to the main form.

I am still putting my tables together for this but I know this is where I will get stuck.

Maybe there is a sample database I can look at?

Thanks for steering me in the right direction.
