Looking at just the page containing the menu, the reference to the .js file inside it is broken:
Code:
<script type="text/javascript" src="ddaccordion.js">
/***********************************************
* Accordion Content script- (c) Dynamic Drive DHTML code library (www.dynamicdrive.com)
* Visit http://www.dynamicDrive.com for hundreds of DHTML scripts
* This notice must stay intact for legal use
***********************************************/
</script>
You need to fix the path in red below so it references the .js file on your server correctly.
