I have an urgent question, and thank you in advance for answering this. I am attempting to setup a form to allow multiple families to sign up under one medical "account". The total monthly subscription fee is calculated by the number of family members selected from a dropdown product menu. A "Form Total" field calculates this subtotal monthly payment on the first page. A one time $100 "setup fee" needs be charged if customers select a "month-to-month subscription" from a product dropdown form. If customers select an "18-month agreement" from that same dropdown form, the "setup fee" is $0. I need to add the subscription subtotal + the setup fee, and have a grand total field just above the credit card field (on the last page).
I tied an Authorize.Net feed and credit card form to a "Form Total" field. However, there is no way to subtotal or create a grand total. Even though I enabled a "Setup Fee" in the feed form (and assigned a price via product dropdown), I am unable to generate a final total field that will calculate both the first month's payment, plus the sign-up fee. It's strange that this isn't in your documentation, since you have the additional "Setup fee" option.
