the confirm page is missing the following code at line 1:
<?php
//WA eCart Include
require_once("WA_eCart/eCart1_PHP.php");
?>
<?php
$eCart1->GetContent();
?>
<?php
// WA eCart Redirect
if ($eCart1->redirStr != "") {
header("Location: ".$eCart1->redirStr);
}
?>
actually, the checkout wizard should have added other code to the confirm page as well, for processing the order through the gateway.
I would delete the checkout pages and re run the checkout wizard.
