Flash widget fails inside Typolight

I have purchased a flash widget

It works fine when I run it outside TypoLight , ie. double clicking a .htm page containing:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en">
<head>
<title></title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<script type="text/javascript" src="swfobject.js"></script>
<script type="text/javascript">
var flashvars = {};
flashvars.xml_path = "xml/starburst.xml";
flashvars.css_path = "xml/styles.css";
var params = {};
var attributes = {};
swfobject.embedSWF("starburst_externalxml.swf", "sb", "590", "300", "9.0.0", "expressInstall.swf", flashvars, params, attributes);
</script>
</head>
<body>
<div id="sb">

</div>
</body>
</html>

But when I integrate the code into an article, like so:

<script type="text/javascript">
var flashvars = {};
flashvars.xml_path = "starburst/xml/starburst.xml";
flashvars.css_path = "starburst/xml/styles.css";
var params = {};
var attributes = {};
swfobject.embedSWF("starburst/starburst_externalxml.swf", "sb", "590", "300", "9.0.0", "expressInstall.swf", flashvars, params, attributes);
</script>
<div id="sb">
[nbsp]
</div>

I just get a black stage

Thoughts?
