Field of order quantity?

[Pav]

I have answered this one in your other post:

I need more order details, how I can get that?

I need more order details, how I can get that? Like quantity, number of credits, etc. current I am getting only PayStatus, InvoiceTotal,Id,ContactId,JobId with following code. app = new iSDK; $invoiceId = $_GET[‘orderId’];; if($invoiceId!=“”) { $qry = array(‘JobId’ => $invoiceId); $rets = array(‘Id’); $cards = $app->dsQuery(“Invoice”, 100, 0, $qry, $rets); //print_r($cards); $invoiceId=$cards[‘0’][‘Id’]; $returnFields = array(‘Id’, ‘ContactId’, ‘JobId’,‘PayStatus’,‘InvoiceTotal’); …

It is the “OrderItem” table.
