I'm trying to get an advertisement placed at the top of my web links section on the web site but it's not working.  I turned off the WYSIWYG editor and placed the code:

<script type="text/javascript" language="javascript" src="http://www.nayouth.com/components/com_ijoomla_ad_agency/ijoomla_ad_agency_zone.php?zid=120"></script>

at the top.  When you view contents the web page you see it in the script.

Any clues on how to do this?
