I'm trying to sell subscriptions that are billed ever 1, 2, or 3 years. For example, for a 3 year subscription, in the Paypal Pro Form shortcode, I use the following parameters: rp="3" rt="Y". However, only the 1 year options works, with the other options resulting in this error message:
"Invalid Payflow form configuration. Invalid “rt, rp, rr” attributes. Payflow supports a specific set of recurring intervals. Pro Forms can be configured to charge: weekly, bi-weekly, monthly, quarterly, semi-yearly or yearly. Any other combination results in this error. This is a Payflow limitation."
Is there any known update, workaround, or hack on this issue? This limitation takes a major blow at my potential income.
