I turned on PHP error reporting and I see the following error when I go to the Cart page,
Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/content/g/e/o/georgevargas1/html/shoppingcart.php:5) in /home/content/g/e/o/georgevargas1/html/WA_eCart/WA_eCart_Definition_PHP.php on line 465
Also when I hit the continue shopping button I get,
Warning: Cannot modify header information - headers already sent by (output started at /home/content/g/e/o/georgevargas1/html/shoppingcart.php:5) in /home/content/g/e/o/georgevargas1/html/shoppingcart.php on line 167
