I have a webpage for a product store split into three frames
top_half - Displays the product details and quantity that the user wants to add when a product is selected.bottom_half of the frame displays the shopping cart when I select 'Submit' in the top half.I want to submit the information from the shopping cart(bottom_half) to display the contents in the top_half as well as an order form for customer details.. this will close the session and display " to complete checkout please fill in the information above"
Cart.php (bottom_half)

session_start();
