jquery nothing happens.

Hi,
I've never had this problem with jQuery so maybe a second pair of eyes will help.

When I run this code, nothing happens:

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"
type="text/javascript"></script>
<script src="/js/jquery.scrollTo-1.4.2-min.js" type=""></script>
<script src="/js/jquery.localscroll-1.2.7-min.js" type=""></script>
<script src="" type=""></script>
<script type="text/javascript">

$(document).ready(function()
{
alert('thedocument is ready.');
$.('#casa').hide();
});

</script>

Any ideas?
