Here's what I had done that solved the issue for me:
There is a line of code in the orders.php file (located in the admin/includes/classes folder) which was causing the error. I commented out the line and then redefined the variable to something that was defined...
// $zc_coupon_link = '<a href="javascript:couponpopupWindow(\'' . zen_catalog_href_link(FILENAME_POPUP_COUPON_HELP, 'cID=' . $coupon_link->fields['coupon_id']) . '\')">';
$zc_coupon_link = '<a href="www.mywebsite.com">';
Since doing this hardcode for the link - I've been able to pull in all orders from zencart into stamps without a problem. The integration works well and has been a time saver for shipping.
Thanks for the posting that there is a new version of the .php file for the zencart shipping file from Stamps.com - I'll try it out. :smile:
