I'm using the order total discount code 2.1 with all the bug fixes. I know, I'm using old code but I've tried upgrading & my old version of osCommerce doesn't like it. When I set up a fixed discount, the order total isn't being calculated correctly if I have multiple items in my cart. For example, with $89.90 worth of merch. in my cart totaling 5 items, I use an $80 fixed discount code and only $78.28 is taken off. With 1 $82 item in my cart, it works fine. Any ideas?
