Thanks for the response Ray. I did as instructed and now the confirm page comes up with
Call to undefined function wa_ecart_ups_setsessiondefaults() in /webroot/a/d/adose001/www/confirm.php on line 61
Line 61 is as follows
59 }
60 else if (!isset($_SESSION["WA_Store_Cart_UPS_Success"])) {
61 WA_eCart_UPS_SetSessionDefaults($WA_Store_Cart);
62 }
