I am looking for a method to subtotal a currency format column on a form. I need a group-by method, and then subtotal the currency values, much like can be done on an Access report. For example, column 1 is part number, column 2 is part quantity, and column 3 is part cost. I need a group on part number, and subtotal part quanity and part cost for that part number group. It's easy to do on a report, but I must be overlooking something simple to be able to do the same thing with a form.
