No confirm.php page; 'no items in cart' on confirm_cart.php page
When I click submit after entering the Customer Information, there's no 'Complete Order' step (confirm.php doesn't load). It loads the confirm_cart.php page and sends an email receipt. There's also a 'no items in cart' at the bottom of the confirm_cart.php page, which empties all the products from the session.
All the pages exist and can be viewed live.
