Problem with "VirtueMart Featured Products" module

Hi,I have successfully install joomla free template relief. I would like to add extension of "VirtueMart Featured Products" under user2 layout. After I added the module, "VirtueMart Featured Products" cannot be shown at my site. Please advice.

Go to "View Source" of your page and check if you have maybe multiple javacript framework references. By that I mean jQuery,mooTools ...

thanks for your prompt reply. i found below coding at my page...do they mean multiple?
<script type="text/javascript" src="/media/system/js/mootools.js"></script>
<script type="text/javascript" src="/media/system/js/caption.js"></script>
also for jquery, i found this
<script type="text/javascript" src="/templates/hot_relief/js/jquery.min.js"></script>
<script type="text/javascript">
jQuery.noConflict();
</script>

<!-- top menu -->
<script type="text/javascript">
function mainmenu(){
jQuery(" #nav ul ").css({display: "none"}); // Opera Fix
jQuery(" #nav li ").hover(function(){
jQuery(this).find('ul:first').css({visibility: "visible",display: "none"}).show(0);
},function(){jQuery(this).find('ul:first').css({visibility: "hidden"}); });}
jQuery(document).ready(function(){ mainmenu();});
</script>

what should I do next? Please advice. Appreciate your help!

that is ok, by mutiple for example if you see "jquery.min.js" twice or "/mootools.js"

I have checked my source code, can't find any multiple .js. If problem not related to .js, may I know what is the problem that caused the module cannot be displayed? thanks again!
