That did add the missing server behaviors
If I copy the cart and store1_PHP and move them into the site root directory where the checkout.php is located. When trying to check-out it says the cart is empty.
If instead I use the copy of the cart and store1_PHP inside the WA_Cart Folder I get the message
The requested URL /cart.php was not found on this server.
