What does this mean?
the form action in the "Shopping Cart" page is:
<form action="<?php echo ($_SERVER["PHP_SELF"].(isset($_SERVER["QUERY_STRING"])?"?".htmlentities($_SERVER["QUERY_STRING"]):""));?>" method="post" >
The form action in the "Customer Info" page is:
<form action="TWF_Artisans_Checkout.php" method="post" name="ecart_customerinfo_form" id="ecart_customerinfo_form">
A PHP string vs. a page location means . . .?
