JQuery :: Vertical Scroller For Contents On Website

I am trying to introduce a vertical scroller to my site, I got the code from a tutorial and slightly tweaked the html to meet my needs but now the content doesn't scroll. None of this code has been altered!
<script type="text/javascript">
$(document).ready(function(){
$(".newsticker-jcarousellite").jCarouselLite({
vertical: true,
hoverPause:true,
visible:10,
auto:500,
speed:1000
});
});
</script>

This is the HTML and PHP part:
<div id="newsticker-demo">
<div class="newsticker-jcarousellite">
<br/><?php
$query = mysql_query("SELECT * FROM employers WHERE featured = 'Yes' AND image != '' ORDER BY rand()");
$i=0;
//$query = mysql_query("SELECT * FROM employers WHERE f_emp_active = 'Yes' and image !='' ORDER BY rand()");
echo '<div>';
while ($aqm=mysql_fetch_array($query)){
?><div><div>
<div class="thumbnail">
<div align="center"><a href="company.php?companyname=<?php echo $string ?>">
<img src="<?=$fullurl?>/thumbnail.php?gd=2&src=employers/logo/big/<?=$aqm[image]?>&maxw=<?=$a18[width]?>" alt="<?=$aqm[companyname]?>" title="<?=$aqm[companyname]?>" class="noborder" /></a>
</div></div>
<div class="clear"></div>
</div></div><br/><br/><?php
if($i==5){
echo '</div><div>';
} $i++;
} echo '</div>'; ?>
</div></div>
