Where do I put a tracking pixel for an affilaite network?

[beejeebers]

I run a zen cart site and I need to place the tracking pixel from the affiliate network on my zen cart "thank you for your order" page. I'm using a custom theme and cannot find where to put this pixel code?

Also, can I just echo $zv_orders_id in the pixel code to pass the transaction id through the pixel code?

Any help is appreciated, I have searched the forums and was surprised there isn't much on this issue. (Unless I'm just searching for the wrong terms?)

The template is tpl_checkout_success.php.

As this page already outputs the order ID, you will be able to see there how you can access it, but how you use it in conjunction with your affiliate code, would depend upon that code.

Thank you, where is that file located?
