I want to use a jQuery plugin (jQuery Tools - Scrollable) to display a carousel.

When I do this outside Umbraco, there is no problem. When I do this inside the Standard Website MVC template for Umbraco 4.11 there is an error.

Code:

<script type="text/javascript" src="http://cdn.jquerytools.org/1.2.7/full/jquery.tools.min.js"></script>
    <script type="text/javascript">
        $(document).ready(function () {
            $("div#slideshow").scrollable({ circular: true, mousewheel: true }).autoscroll({ autoplay: true });
        });
    </script>

Only when I use this in my Umbraco theme, the following error displays, the file with jQuery and jQuery Tools IS accessible. Why is the plugin not added to $.fn ?

Error:

Uncaught TypeError: Object #<Object> has no method 'scrollable'
