I'm setting up a subscription with multiple choice options but whenever I submit the form and login to PayPal, I get this error:
"The link you have used to enter the PayPal system is invalid. Please review the link and try again."
It happens both in production mode and test mode. The multiple choice was setup with a product pricing field, as I understand PayPal doesn't do subscription donations. Subscriptions setup on another site work fine, as do the two other non-subscription donation forms on this site. I tried changing settings but nothing helped.
The form is here:
http://www.duttonfarm.org/get-involved/gifts-donation/sustaining-donation-form/
I can provide WP login if necessary.
Thanks
