I am having a problem with my shopping cart. The shopping cart is creloaded, and is based on oscommerce. In the "salemaker" section, some of my products are not getting the sale applied to them. I'll click on the products that I want to recieve the sale, but when I click submit and the page reloads, those items become unclicked. Our store is having a huge sale coming up very soon and would like this problem to be fixed.
