I would like to charge a processing fee for paying customer's supplies. I have a 1% set up in the item. After I enter the item charge, I add another line right below for Processing Fee. It comes out fine and calcullates the 1% charge. I save the invoice. When I return to the invoice form, the processing Fee line is there but the Charge column is 0. In fact I can't even manually enter a charge as it turns to 0.
Trying to find out the problem. Thanks
