Add function to CCGV(trad), OSCommerce

CCGV(trad), [login to view URL], have the database tables restrict_to_products and restrict_to_categories. If you’re into oscommerce and ccgv(trad) you will now that you can restrict discount coupons to certain categories and products by adding id's into these fields. What I need is to add functions opposite of this, a field for exclude certain products and a field to exclude certain categories from discount coupons. The function for restrict_to_products and restrict_to_categories should not be replaced, I want to keep that. This will result in the options to exclude products and categories from discounts, by adding the proper id’s in admin while setting up a new discount coupon. I will provide you with my files, that I have attached to this project. catalog/includes/modules/order_total/[login to view URL] and admin/[login to view URL] I believe these are the only files that need to be modified. I will not give you any FTP access. If you need any more info, feel free to ask me.
