I set up a gravity form integrated with a Paypal subscription, however when I tested the form, I was taken to an error page on PayPal:
This feature is only available to Business and Premier accounts.
Return to merchant (which goes to a blank page)
http://www.training.gfpbusiness.com/twitter-angels/ this is where the form is.
I just cannot work it out and have spent hours on this. Please can somebody help me out.
