Update line 17 of binDetails.php from:
$cardProductRS->bindParam("i", "".($_SESSION['WADA_CardType_Insert']) ."", "-1"); //ParamSessioncardProductID
to:
$cardProductRS->bindParam("i", "".(isset($_SESSION['WADA_CardType_Insert'])?$_SESSION['WADA_CardType_Insert']:"") ."", "-1"); //ParamSessioncardProductID
The charts page has a lot of hand code. It would have to be updated by hand. If you want I can help with that in a premier support ticket.
