You need to use jQuery.noConflict().
ex:
<!– New jquery ui version –>
<link rel=”stylesheet” type=”text/css” href=”http://ajax.googleapis.com/ajax/libs/jqueryui/1/themes/redmond/jquery-ui.css”>
<!– jquery ui function for the new version, changing the ‘$’ to ‘$jq’ –>
<script type=”text/javascript”>
$jq(function() {
// do something
});
</script>
<script type=’text/javascript’>
var $jq = jQuery.noConflict();
</script>
<!– Older jquery ui version –>
<script type=”text/javascript” src=”js/jquery-1.4.1.min.js”></script>
