I don't see how to have member discounts to fee based fields. And then from there having a fee based field also different for a coupon code (so the coupon code would change the field prices, not just a global amount.)
Please help. we are trying to start this event!!!
I saw conditional fields in your tutorial, but there isn't anything that shows how a fee can be discounted for members or a fee field can be subtracted based on coupon.
