Hello everyone, my name is Rodolfo  and i am a student at the dresden
university of technology (Germany)
could someone please tell me how do i make this plugin to work
correctly i have downloaded the hole source and I linked it to my html
archive:

<script type="text/javascript" src="jquery-1.2.2.min.js"></script>
<script type="text/javascript"  src="interface 1.2/interface.js"></
script>
