hiding a dom element that originates from external script

hiding a dom element that originates from external script

#1 There is a projectwonderful script included in the clients WP blog and it creates code for ad box. 

#2 Client wants to hide the text link below the graphical ad after it's all created.   So I thought a very simple javascript to hide it would be easy.  I checked in firebug and the script is loaded & syntactically correct.  But it is not hiding the element.   I'm trying to use the DOM inspector in firefox but I can't make head or tails of it. 

#3 HERE IS THE SCRIPT I load it in the head of the WP

var $jq= jQuery.noConflict();
$jq(document).ready(function() {
       $jq('a[href~="projectwonderful.com/advertisehere"]').hide();
     });

Here is link to the blog http://comix.dorkage.net

What can I do to make this thing hide?  Thank you.
