Simple Panel Script from not working, closing script tag incorrect?

Below is a script that I am using and has always worked, however lately in
my wordpress site, dreamweaver is picking up the closing tag as incorrect?
Is all my mark up below correct?
I haven't changed anything, but now it's playing up, I cannot work out the
problem?
<script>
$j = jQuery.noConflict();
// perform JavaScript after the document is scriptable.
$j(document).ready(function() {
// setup ul.tabs to work as tabs for each div directly under
div.panes
$j("ul.tabs").tabs("div.panes > div#panel");
});
</script>
