src attribute in div not recognized

src attribute in div not recognized

Hi,
I'm trying to use jquery (for the 1st time) in the following default.aspx page

<%@ Page Language="VB" AutoEventWireup="false" CodeFile="Default.aspx.vb" Inherits="_Default" %>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
<script src="Scripts/jquery-1.3.2.js" type="text/javascript"></script>
<script src="Scripts/htmlparser.js" type="text/javascript"></script>
<script src="Scripts/UFrame.js" type="text/javascript"></script>
<style type="text/css">
div.UFrame
   {
    width: 300px;
    height: 300px;
    overflow: scroll;
    border: 1px solid black;
    background-color: white;
    color:black;
    padding: 5px
   }
div.box
   {
    float: left;
    width: 310px;
    margin: 5px
   }
        fieldset.testarea { background-color: #4F4F00; border:none; width: 1000px; margin-bottom: 20px; padding: 10px; }
        fieldset.testarea em { color:green; }
        fieldset.testarea a { color:blue; }       
        fieldset.testarea h3 { font-size: 1em; height: 2.5em; }
        div.no { font-size: 4em; font-family: Georgia,"Times New Roman",Times,serif; }
     
</style>   
</head>
<body>
<form name="UFrameTest" method="post" action="Default.aspx" id="UFrameTest">
    <fieldset class="testarea">
        <div class="box">
            <div class="UFrame" id="UFrame1" src="EmployeesPage.aspx?ID=UFrame1" >
                  <p>this should get replaced with content from EmployeesPage.aspx</p>
            </div>   
    </div>
    </fieldset>
    </form>
</body>
</html>


I copied the code from the UFrame example and have included the 3 js files in my project.
The problem is the "src" attribute in the <div id=UFrame1" is not recognised and throws the following exception:

"Syntax error, unrecognized expression: " + expr;
where expr = src

Any ideas what I'm doing wrong.

Thanks for any help.[/b]
