Is there a way to add a discount option of some sort? I've tried using a Product option with negative values in it, but I end up just getting a Paypal error. The form is located here: http://nesoftball.org/?page_id=222 .
Also, another quick question. I didn't really know what to call this one so I didn't know how to look for it in the forums, but I was wondering how to make the options where it asks if you're registered or not, if you say "Yes" if the field where you enter in your number becomes Required.
Any and all help is appreciated! :)
