I need someone familiar with X-Cart's check out routines to change the check out such that coupons do not deduct from the final total, but rather just from the sub-total. Also, if the coupon is for MORE than the subtotal, it must not go into the negative. ie: Subtotal: $150 Coupon: $200 Shipping: $25 Final Total: $25 X-cart's code is php/mysql based and uses Smarty Templates. Anyone familiar with those can probably make the changes. I know which php modules need to be modified, I just am not a good enough coder to know how to pull this off. I will provide you with access to the website and the X-Cart code once we've settled on the pricing.
All X-Cart php modules needed to perform the required cart calculations correctly. (I estimate only needing to modify 2)
It will run on a Linux Apache webserver and interfaces with a mysql dbase.
