MarketPress Coupon Not Connecting To PayPal


I have a customer trying to buy a class. YAY! The customer is having a problem. The paypal won’t go through.

I set up a coupon code to buy my class for $0.50 to test the purchase process. The coupon works in coursepress/marketpress but when the PayPal opens to my checkout the course is $25, no coupon code reflected. Please help. Thank you.
