I thought I had seen a feature that allowed me to show only one payment system on the registration page and then show a second option only if the first payment attempt didn't work. I can't seem to find this feature now. Was I dreaming? Can I find this somewhere?
oooooooooooooooooooo!! I figured it out on my own! I simply removed one gateway from the payment system configuration in the forms editor. The second gateway still shows if the user is redirected back in case of a declined transaction.
