Does the code appear in the html for the success page? What I mean is, when you place an order, and you go back to the success page, is you view the source of this page, can you see the javascript?

It sounds like your code is either being omitted, or skipped. This could either be due to a javascript error, or its in the wrong file, or its placing within the correct file.

Which tpl_success file have you placed this code within? What is the EXACT path to this file within your website? Which template does your site currently use?

I didn't really want to place a test order, as even if I place one, I would have no way of checking the statistics.
