Navigation bar problem

Hello everyone. When I’m trying to implement some photos with thumbnails onto my page (, the scrolling of the navigation bar stops. It was supposed to move down as I was advancing over the topics. I am loading the JS scripts in this order:

<script charset=“utf-8” type=“text/javascript” src=“js/jquery-1.10.2.min.js”></script>
<script type=“text/javascript” src=“js/jquery.backgroundposition.js”></script>
<script type=“text/javascript” src=“js/jquery.smooth-scroll.js”></script>
<script type=“text/javascript” src=“js/sp.js”></script>
<script type=“text/javascript” src=“js/js.js”></script>
<script type=“text/javascript” src=“js/skins.js”></script>

<script src=“js/lightbox-2.6.min.js”></script>
<link href=“css/lightbox.css” rel=“stylesheet” /> -These are the thumbnail files.

I want to know what should I do to manage to get both the thumbnail and the navigation bar scrolling working at the same time.

I have no idea…
but these are two of the errors I got when visiting your site (and half of the photos weren’t finished loading)

Line: 49
Error: Object doesn’t support property or method ‘curCSS’

Unexpected character: U+002D HYPHEN-MINUS (-)
File:, Line: 94, Column: 7

I have fixed the first one, the second one is just a comment.
