Move the following bit of code to where it is just underneath the <body> tag:
Code:
<!-- PHP generated menu script [any modules or extensions must come AFTER this] -->
<script type="text/javascript" src="udm/udm-dom.php"></script>
Also, you need these three scripts inside the <head> section of your page:
Code:
<!-- ULTIMATE DROP DOWN MENU Version 4.5 by Brothercake -->
<!-- http://www.udm4.com/ -->
<script type="text/javascript"
src="udm/udm-custom.js"></script>
<script type="text/javascript"
src="udm/udm-control.js"></script>
<script type="text/javascript"
src="udm/udm-style.js"></script>
Make sure those files are on the server as well.
