Hi.

I'm running on a filemaker pro "Business productivity Solution" Template. It runs fine but I'm Having trouble auto updating my inventory quantity field using the quantity entered in the Sales order.

Exemple: Original Inventory Qty = 10

Sales order Qty = 2

New Inventory Qty should be 8, but remains 10.

Thanks for your help.
