JQuery Qtip not working in IE

Question

I am using the QTIP plugin to create a tool tip over some text. It works great in firefox but not in IE. my code for the page looks like this

<script type="text/javascript">
  $(document).ready( function() {
        $("#label_PERSONAL").qtip({
              content: 'this is a test!',
              show: 'mouseover',
              hide: 'mouseout'
         });
  });
</script>


<div id="main">
     <label id="label_PERSONAL">Personal Inforamtion</label>
</div>
