Summing field for a subgroup of records

E

Etienne

Hi,

I am new to Access VBA and need to know how to accumulate a field in a
variable according to the value in another field and show the cumulative
value in a textbox in a form. Example: I have several records of the same
product and need to show in a form the cumulative qty of each product after
the quantity is entered.

I will appreciate any help.

Thanks,

Etienne
