I have created a Political Donation form using Gravity Forms. I have created radio buttons with preset amounts, but I also had to create a separate field in which the user can enter their own amount.
I installed the PayPal Standard plugin add-on and had to problem mapping the fields of the form to be passed to PayPal to conduct the transaction.
It dawned on me that I didnt map the User Defined field to be passed to PayPal in the event that the user chose that options. As I look the mapping. I dont see where you can make the donation amount, or is that something they will have to enter after clicking submit?
