Missing something simple

Missing something simple

I'm trying to implement scrollTo functionality on document ready, but running into a problem (it's not scrolling... to).

However, currently i'm having an even simpler problem...
Given the following html, i expect an alert box to display the offset position, but i get 'null'.
Am I missing something?
  1. <html>
    <script type="text/javascript" src="jquery-1.4.2.min.js"></script>
    <script type="text/javascript" src="jquery.scrollTo-1.4.2.min.js"></script>
    <script type="text/javascript" language="javascript">
        function showResults() {
            alert($('div#a').position());
        }
        $(document).ready(showResults());
    </script>

    <body>
    <div id="a">
    <h1>Test</h1>
    </div>
    </body>
    </html>














Thanks
