Trying to add javascript but keeps appearing at top of page and not in order

Hi folks,

I’d like to add this piece of code to header.php:

<script type="text/javascript">
		$(function() {
            $("#navmenu").lavaLamp({
                fx: "backout",
                speed: 700,
                click: function(event, menuItem) {
                    return true;
                }
            });
        });
    </script>

I am placing it before the php code to call Jquery:

<?php wp_enqueue_script("jquery"); ?>

But it always appears BEFORE the jquery include and generates an undefined error.

Can anyone please help me get this to render after the jquery file include?

Thanks again
