Selectivizr Help Please
I am trying to use Selectivizr - but for some reason it's not working (I'm testing my site on Adobe Labs). 
I've been looking for solutions & I can't see what I'm doing wrong.
Is there something I'm missing? Any help would be greatly appreciated.

.ps - modernizr, mootools & selectivizr are in the Root Folder (so I know the Paths are correct)

 *Here is the HTML --

    <!DOCTYPE HTML>
    <html class="no-js">
    <head>
    .
    .
    <link rel="stylesheet" href="css/main.css" media="screen, projection">
    <script type="text/javascript" src="modernizr.custom.76989.js"></script>
    <script type="text/javascript" src="mootools-core-1.4.5-full-compat-yc.js"></script>
    <!--[if (gte IE 6)&(lte IE 8)]>
    <script type="text/javascript" src="selectivizr-min.js"></script>
    <noscript><link rel="stylesheet" href="css/main.css" /></noscript>
    <![endif]-->
    </head>
