jquery vertical scroll with mousewheel

Question

Hi

I have div containing images that I want to scroll up and down using the jquery mousewheel plugin. Not sure how to do this, the documentation is not very helpful would be grateful for any suggestions.

<div class="innerScroll" style="float:left;width:448px;height:500px; overflow:hidden;">
<div class="mediaPanel"><img src="media/poster_silence.jpg" alt="" /></div>
<div class="mediaPanel"><img src="media/poster_comingsoon.jpg" alt="" /></div>
<div class="mediaPanel"><img src="media/poster_comingsoon.jpg" alt="" /></div>
<div class="mediaPanel"><img src="media/poster_comingsoon.jpg" alt="" /></div>
<div class="mediaPanel"><img src="media/poster_comingsoon.jpg" alt="" /></div>
<div class="mediaPanel"><img src="media/poster_comingsoon.jpg" alt="" /></div>
<div class="mediaPanel"><img src="media/poster_comingsoon.jpg" alt="" /></div>

<script type="text/javascript">

$('innerScroll').bind('mousewheel', function(event,delta){ if (delta > 0) {

} else {

} });

if you're using this file jQuery_mousewheel_plugin.js

$('.innerScroll').mousewheel(function(event,delta){

    var media = $(this).find('.mediaPanel');
    if (delta > 0) {
        media.css('top', parseInt(media.css('top'))+40);
    } else {
        media.css('top', parseInt(media.css('top'))-40);
    }        
});
