Hi Eduan, the issue is now with what the form looks like, its a problem when you submit the form, please read my original post, all the details are in it:
"I've upgraded to pro today and used the short code [s2Member-Pro-PayPal-Form register="1" level="0" ccaps="" desc="" custom="newarkbus.scobib.co.uk" tp="0" tt="D" /] to add a registration form to this page
http://newarkbus.scobib.co.uk/about-the ... -a-member/
However, when you try to submit the form is says "PayPal® configuration error. Please configure your PayPal® Email Address.""
Cheers,
Zoe
