This shows that you are not using jquery plugin which need to be put at the top.
Before any jquery plugin
download jquery from here
http://jquery.com/download/[
^]
either download or you can use CDN link also
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js">
once you put this in your file then put your jquery plugin
<script type="text/javascript" src="/js/jquery.jqDock.min.js"></script>
Cheers
