We are working with a modified version of the Credit Class & Gift Voucher contribution ([login to view URL],282/category,all/).
At this moment, people can only enter one coupon at checkout. I would like them to be able to enter multiple coupons. So, for example I have two coupons of €10,- I enter them both and get €20,-.
I need somebody to fix this at our site [login to view URL]
