X-Cart forums - Adding security cert image...with java script in head. How?

I use thawte for my security cert.

I am trying (unsucessfullly) to add the script to the head:

Code:

<SCRIPT LANGUAGE="JavaScript">

<!--

 function OpenCertDetails()

 {

thewindow =window.open('https://www.thawte.com/cgi/server/certdetails.exe?code=XXXXXX', 'anew',config='height=400,width=450,toolbar=no,menubar=no,scrollbars=yes,resizable=no,location=no,directories=no,status=yes');

}

// -->

</SCRIPT>

And then in the body, left hand side of the store pages, underneath HELP section, I need to add the image:

[img]PATH_TO_STATIC_IMAGE.gif[/img]

I tried to add the javascript to the template in customers folder...where I found the <head> </head> info but this only caused an error that was something about smarty.

How can I do this? Thanks in advance!
