Hello
I have a text box in the footer of the subform called Tot_qta where I sum the field "qta" = sum ([qta]).
Then I have a text box in the main form that should make me see this total.
The name of the subform control is "maschera_item"
If I put = [Maschera_item]. [Form]! [Qta], obviously shows me the quantity of the first row
if I replace qta with tot_qta it gives me error.
Can somebody explain me how to solve this issue?
Many thanks
