I installed the Define Pages - Shopping Cart, but for some reason it did not work so I uninstalled it, and installed the other shopping_cart_text_v1-0 that didn't work so i uninstalled it as well, but now my shopping cart isn't working properly. It's adding the products to the cart but it's not displaying the items. The only thing showing up on the page is "Your Shopping Cart Contents". How can u get the items to show back up with someone add items to there shopping cart?
