Order number missing from confirmation emails
I have a new site I've been working on and I'm having a problem with the confirmation email: There's no order number printed out.
The code to make it print is:
<h3 style="font-size:small; margin:2px 0; color:<Text_Dark />; /* Text_Dark */" >Order number: <?php echo ((isset($_SESSION["gardencart_OrderID"]))?$_SESSION["gardencart_OrderID"]:"")?></h3>
I've compared it to another site I've done who's order confirmation works, and they seem the same:
The only different is gardencart_ vs eCart1, which is correct.
I'm attaching the confirmation page that contains the UniversalEmail object. Could someone please look at it and tell me why the order number does not come through? Everything else is coming through and being echoed into the email message just fine.
