[jQuery] errors using carousel lite plugin

[stef]

cant get this to work, even though ive just taken over the exact code
from the demo. im trying to make it scroll autmatically through a set
of images. my js is

$(document).ready(function(){
      $(".anyClass").jCarouselLite({
         auto: 800,
         speed: 1000
     });
 });


html:

<div class="anyClass">
    <ul>
        <li><img src="http://www.google.be/intl/en_com/images/
logo_plain.png" height="110" width="279" /></li>
        <li><img src="http://www.google.be/intl/en_com/images/
logo_plain.png" height="110" width="279" /></li>
       <li><img src="http://www.google.be/intl/en_com/images/
logo_plain.png" height="110" width="279" /></li>
        <li><img src="http://www.google.be/intl/en_com/images/
logo_plain.png" height="110" width="279" /></li>
    </ul>
</div>

the error i get in firebug is:

tLi.gt is not a function
ul.prepend(tLi.gt(tl-v-1).clone()).append(tLi.lt(v).clone());
