I have a form that I need to perform several percentage calculations on for taxes and gratuity. So I have 3 "total" fields. The first just totals up all the products. The second I need to take the product subtotal and add 10% to it. So I wrote the following formula:
'( {Product Subtotal (Price):33.2} * 0.10) + {Product Subtotal (Price):33.2}'
This doesn't seem to be working though. Am I missing something?
