body: <p>I am trying to make this <a href="http://www.webdesignbeach.com/beachbar/ajax-fancy-captcha-jquery-plugin" rel="nofollow noreferrer">captcha</a> jquery plugin to work. The a certain line of code is executed, the error pops up.</p>
  
  <p>This is the line of code that causes the error :</p>
  
  <pre><code>$(".ajax-fc-" + rand).draggable({ containment: '#ajax-fc-content' });
  </code></pre>
  
  <p>What I am assuming is that there is some kind of conflict with the javascript reference, but can't determain what.</p>
  
  <p>These are the referenes that I am using</p>
  
  <pre><code>&lt;script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.3.2/jquery.min.js"&gt;&lt;/script&gt;
  
  &lt;script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.7.2/jquery-ui.min.js"&gt;&lt;/script&gt;
  &lt;script src="js/ui.core.js"&gt;&lt;/script&gt;
  &lt;script src="js/ui.draggable.js"&gt;&lt;/script&gt;
  &lt;script src="js/ui.droppable.js"&gt;&lt;/script&gt;
  &lt;script src="js/effects.core.js"&gt;&lt;/script&gt;
