add item to cart

mindapolis · August 12, 2011

if someone could PPPPPPPPPPLLLLLEEEEEEEEAAAAAAASSSEEEEEE help me, I would really appreciate it. I got rid of the error message and if you click a treat on treats,php it will redirect to the checkout.php and it displays the table header but not the chosen treat.

treats.php

require_once("functions.php");
//session_name("treats");
