I pestered you for a while to get my Paypal button to include a custom variable to direct the customer to the correct Thank you page after transaction. So i have been using cv1 and it has worked fine but i just found out it is conflicting with WP Affiliate plugin (that integrates with s2M) as that plugin uses cv1 as the Affiliate ID. What happens is that i get my s2M variable when i try to check which affiliate generated the sales!
So the question is this one: in the Paypal button, can i use cv2 as my custom variable for the Thank you page and skip the cv1?
