[Contribution] Discount Coupon Codes in General Add-Ons Support Posted August 3, 2010 I checked all the files, and they are the same. The system is displaying the coupon code in the checkout confirmation page, it's just not calculating it into the total. It shows how much the discount is 'Discount code [VIDEXP] applied - -$24.00 but the total still stays the same. I just did some trouble shooting, and found out that the only way it DOESNT work is when you do not include the code into the sub total. If you leave it out the TOTAL does not change, only when you combine it with the sub total.
