Add Javascript popup on checkout_success?

Hey all, quick question for you...

is it possible to have a javascript popup on the checkout_success page? this is the code:

<script type="text/javascript"><!-- // Adjust the values of popup_pos_x, popup_pos_y to change the location of the popup layer on your confirmation page popup_pos_x=50; popup_pos_y=50; // fill in the order number below popup_order_number = '<?php echo $zv_orders_id; ?>'; // fill in the email address below popup_email = '<?php echo $orders->fields['customers_email_address'] ; ?>'; //--> </script> <!-- PriceGrabber Merchant Evaluation Code --> <script type="text/javascript" charset="UTF-8" src="https://www.pricegrabber.com/rating_merchrevpopjs.php?retid=11668"></script>

<noscript><a href="https://www.pricegrabber.com/rating_merchrev.php?retid=11668" target=_blank>
<img src="https://images.pricegrabber.com/images/mr_noprize.jpg" border="0" width="272" height="238" alt="Merchant Evaluation"></a></noscript>

<!-- End PriceGrabber Code -->

I've verified this code with pricegrabber, and it works 100%, but it doesn't want to fire off our checkout_success page. Is there any reason behind this? I don't have my popup blocker enabled...

does anybody have the answer to this?

Hi Sartor,
I wish I could solve this one for you, but clearly you are way ahead of me with coding.
I'm stuck on just trying to add any code at all to checkout_success. All I want to do is add a single line of text containing a link. Got no idea how to edit a .php page. Terrified at the mere prospect. All clues appreciated.
Keeping my fingers crossed that you get an answer.
