Hey help??

Have you included the jQuery library in your page, and put that line changing the value in the correct place?

Something like this:

<script type="text/javascript" src="location/of/jquery.js"></script>
<script type="text/javascript">
    $(function() {
        $("#hidden_input").val('test');
    });
</script>

see this, could help you http://jsfiddle.net/g2fsQ/

The code you wrote should work. You also may have forgotten this bit of code :

$(document).ready(function(){
    // your code here
});
