Receipts with running total
I am new at Filemaker. Mainly an Excel guy. I'm using Filemaker Pro 11 on a Mac OS 10.5. I am not good at writing (or even implementing) scripts...
I am trying to build a POS (Point of sale) from scratch. My current problem is that I want to include several items on one receipt and have the receipt-total running. Like a cash register in a supermarket. I just get stuck in the subtotal section that seemingly will not let me have more than one subtotal field but I will not be surprised if I am missing something.
Basically I would like to enter one serial number that is then entered in to all items below until I get to a new receipt. This i guess would allow me to use the trailing subtotal function.
I'd appreciate any help.
