I see the JavaScript files aren't loading for some reason on your page... I wonder if your style is missing the hook or possibly a poorly written mod could be hijacking the hook and not letting any other mods use it.
If you want to try and trouble shoot open your headinclude template and look if you have the line:
Code:
{vb:raw template_hook.headinclude_javascript}
anywhere in it... if you don't, add it in at the bottom.
If you just want it to work manually add the following to the bottom of your headinclude template:
Code:
<vb:if condition="THIS_SCRIPT == 'index'">
<script type="text/javascript" src="clientscript/prototype.js"></script>
<script type="text/javascript" src="clientscript/jsProgressBarHandler.js"></script>
</vb:if>
