I've used them before and they worked fine. I've removed them and put them back several times. Can you check my code and see what I've done wrong? Thank you!

Hello Alix.

Your page code seems a little bit disordered.Also there is double include of the jquery library.

<link rel="stylesheet" type="text/css" href="Styles/dmxTabs.css" />
<link rel="stylesheet" type="text/css" href="Styles/jqueryui/flick/flick.css" />
<script type="text/javascript" src="ScriptLibrary/jquery-ui-core.min.js"></script>
<script type="text/javascript" src="ScriptLibrary/dmxTabs.js"></script>
<!-- InstanceEndEditable -->
<link rel="stylesheet" type="text/css" href="Styles/dmxNavigationMenu.css" />
<script type="text/javascript" src="ScriptLibrary/jquery.easing.1.3.js"></script>
<script type="text/javascript" src="ScriptLibrary/dmxNavigationMenu.js"></script>
<link href="Styles/styles-sgt.css" rel="stylesheet" type="text/css" />

Shoule become:

<link rel="stylesheet" type="text/css" href="Styles/dmxTabs.css" />
<link rel="stylesheet" type="text/css" href="Styles/jqueryui/flick/flick.css" />
<script type="text/javascript" src="ScriptLibrary/jquery-latest.pack.js"></script>
<script type="text/javascript" src="ScriptLibrary/jquery-ui-core.min.js"></script>
<script type="text/javascript" src="ScriptLibrary/dmxTabs.js"></script>
<!-- InstanceEndEditable -->
<link rel="stylesheet" type="text/css" href="Styles/dmxNavigationMenu.css" />
<script type="text/javascript" src="ScriptLibrary/jquery.easing.1.3.js"></script>
<script type="text/javascript" src="ScriptLibrary/dmxNavigationMenu.js"></script>
<link href="Styles/styles-sgt.css" rel="stylesheet" type="text/css" />
