I have a course selection field. Course A or Course B. They both cost the same. If you signup for Course A, I would like that to go to Paypal to show that someone is paying for Course A. I put the field variable in the "Add text to invoice" field, and it shows up on the page with the paypal button, but when you click on pay now button, it reverts back to the variable [course].

Is there a way to keep this name all the way to paypal?
Thanks in advanced!
