jquery modal dialog onclick?

Instead of div.thedialog, give div#thedialog. the . is used with class names and # is used when you are working with ids.

( Also, if this is the actual code you used, there was a missing bracket :) )

The working code:

<!doctype html>
<head>
    <link rel="stylesheet" href="http://ajax.googleapis.com/ajax/libs/jqueryui/1.7.0/themes/ui-lightness/jquery-ui.css" />
    <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" type="text/javascript"></script>
    <script src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.7.2/jquery-ui.min.js" type="text/javascript"></script>
    <script type="text/javascript">
$(document).ready(function() {
$('div#thedialog').dialog({ autoOpen: false })
$('#thelink').click(function(){ $('div#thedialog').dialog('open'); });
})
    </script>
</head>
<body>
<div id="thedialog" title="Download complete">
    <p>
        <span class="ui-icon ui-icon-circle-check" style="float:left; margin:0 7px 50px 0;"></span>
