Very Simpe Questions - why I am not able to change the color of span element

 Hi,

I have all the Javascript to change the color of a span ID. But why clicking on the span does not change the color? I think all I need to include is the jquery-1.3.2.min.js file to make the Jquery work. Kindly explain. Thanks.

<script type="text/javascript">

        $("#someID").click(function() {
        $("#someID").css("color", "red");

    });




</script>

<span id="someID">Some Text</span>
