-session storage in mysql during your oscommerce installation

-change to /catalog/admin/modules.php to make admin interface for payment modules operate properly
FROM THIS: while (list($key, $value) = each($HTTP_POST_VARS['configuration'])) {

-in the admin interface for oscommerce, enter the VELOCT account id in the VELOCT payment module
