Hi econcepts,

Thank you for your help, but it is still not working.

I did #1 as requested below, but instead of checkout_success/tpl_footer.php, I deleted the includes/templates/[your template directory here]/templates/tpl_footer.php which is what I thought you meant.
1) DELETE the directory and file found here /includes/templates/[your template directory here]/checkout_success/tpl_footer.php
I then inserted the following code in /includes/templates/[my template]/common/tpl_main_page.php

Code:
<?php
require($template->get_template_dir('.php',DIR_WS_TEMPLATE, $current_page_base,'google_analytics') . '/google_analytics.php');
?>
<?php 
if ($_GET['main_page']=="checkout_success") {

if (isset($zv_orders_id) && (int)$zv_orders_id > 0 && isset($order_summary) && is_array($order_summary)) {

  if (!isset($_SESSION['affiliate_order_id']) || $_SESSION['affiliate_order_id'] != $zv_orders_id ) {

      $_SESSION['affiliate_order_id'] = $zv_orders_id;

     $commissionable_order_formatted = number_format($order_summary['commissionable_order'], 2, '.', '');

     echo '<script language="javascript" type="text/javascript" src="https://www.medsafeglobal.com/jamaffiliates/sale.php?amount=' . $commissionable_order_formatted . '&trans_id=' . $order_summary['order_number'] . '"></script>';

    }

} // end if for determining if this was the checkout_success page.?>
..then...nada, zip, zilch after a test order was placed!



Could it be that because the cart is on a second level heirarchy (like domain.com/cart) that it is the reason why I'm having issues? Hmmmm

Thanks again for your help!
