As the example is written, it will not be parsed by any web browser. It must be replaced with the old example that used to reside on that page:
<script language="JavaScript" src="http://www.livejournal.com/customview.cgi?username=test&styleid=101&enc=js">
</script>
Exibit A - http://www.intrex.net/banker/embedtest/index-a.html - Uses the corrected form
<html>
<body>
<SCRIPT LANGUAGE="JavaScript" SRC="http://www.livejournal.com/customview.cgi?user=maltor&styleid=51600&enc=js">
</script>
</body>
</html>
Exibit B - http://www.intrex.net/banker/embedtest/index-b.html - Uses the old/incorrect form
<html>
<body>
<SCRIPT LANGUAGE="JavaScript" SRC="http://www.livejournal.com/customview.cgi?user=maltor&styleid=51600&enc=js" />
</body>
</html>
When you look at the souce for the blank page on index-b.html you'll notice the script was never parsed be the browser.
