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.
Bill

Bill-
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.
