Trying to add Microsoft AdCenter tracking to my checkout page

I have to put some code in my "Thank You" page but i cannot locate the page.
I am looking for the "checkout_success" page.
Could someone tell me where the location of this page is please?

This is the code:

<script type="text/javascript"> if (!window.mstag) mstag = {loadTag : function(){},time : (new Date()).getTime()};</script> <script id="mstag_tops" type="text/javascript" src="//flex.atdmt.com/mstag/site/66d05c5c-328d-4b48-b797-0a9859b74656/mstag.js"></script> <script type="text/javascript"> mstag.loadTag("analytics", {dedup:"1",domainId:"1631202",type:"1",revenue:"",actionid:"55073"})</script> <noscript> <iframe src="//flex.atdmt.com/mstag/tag/66d05c5c-328d-4b48-b797-0a9859b74656/analytics.html?dedup=1&domainId=1631202&type=1&revenue=&actionid=55073" frameborder="0" scrolling="no" width="1" height="1" style="visibility:hidden;display:none"> </iframe> </noscript>

There is a variable that needs inserting as explained here:

*To dynamically grab the order total (net value), the function or variable from Zen/PHP needs to be inserted between the commas of revenue.
The revenue:"" is a place holder. The commas need to have a function/variable inserted between them.
*

Does any one know what the variable / function is that i need to insert?
Thanks in advance.

You can edit define_checkout_success.php in admin > Tools > Define Pages Editor.

You would echo the order total variable (not sure offhand exactly what its name is) like this:

{dedup:"1",domainId:"1631202",type:"1",revenue:"<?php echo $whatever_variable_name ;?>",actionid:"55073"})

I see, i have added the script in the define pages, however, i now need the variable, whatever it is :smile:
