JQUERY IE bug

JQUERY IE bug

My page works fine for me in FireFox. But, the leftnav (being loaded by JQUERY) won't load in IE. I don't get any JS error messages so I'm stuck!

Here's my JQUERY code
<div id="nav" style="width:126px;">
   </div>
     <script>
      $('#nav').load('flyout_nav_chief3B.asp');
     </script>


Here's a test URL if that helps:
http://qa.chiefsupply.com/

When I alert the returned data like this...I get the correct response...even in IE:
      $.get("flyout_nav_chief3B.asp", function(data){
         alert("Data Loaded: " + data);
      });


Thanks in advance!
