I've currently got a javascipt navigation which uses jQuery,

My problem is that the "sliding box" doesn't rest on the corosponding page.

Here's the following code for the html and css, could anybody have a look for me?

Code:
</style>
<link href="css/layout.css" rel="stylesheet" type="text/css" />
    <script type="text/javascript" src="js/jquery-1.2.3.min.js"></script>
    <script type="text/javascript" src="js/jquery.easing.min.js"></script>
    <script type="text/javascript" src="js/jquery.lavalamp.min.js"></script>
    <script type="text/javascript">
        $(function() {
            $("#1, #2, #3").lavaLamp({
                fx: "backout",
                speed: 1200,
                click: function(event, menuItem) {
                    return true;
                }
            });
        });
    </script>
<style type="text/css">
Code:
    <li class="current"><a href="Index.html">Home</a></li>
    <li><a href="Maintenance.html">Maintenance</a></li>
    <li><a href="Troubleshooting.html">Troubleshooting</a></li>
    <li><a href="Contact.html">Contact Us</a></li>
Code:
        .lavaLampNoImage {
	position: relative;
	height: 35px;
	width: 421px;
	overflow: hidden;
	margin-top: 15px;
	margin-right: 0;
	margin-bottom: 0;
	margin-left: 0;
	padding-left: 15px;
        }
                .lavaLampNoImage li {
                    float: left;
                    list-style: none;
                }
                    .lavaLampNoImage li.back {
                        background-color: #0099FF;
                        width: 9px;
                        height: 30px;
                        z-index: 8;
                        position: absolute;
                    }
                    .lavaLampNoImage li a {
                        font:12px arial;
                        text-decoration: none;
                        color: #333;
                        text-align: center;
                        top: 7px;
                        letter-spacing: 0;
                        z-index: 10;
                        float: left;
                        height: 30px;
                        position: relative;
                        overflow: hidden;
                        margin-left: 10px;
						margin-right: 10px;
                    }
                        .lavaLampNoImage li a:hover, .lavaLampNoImage li a:active, .lavaLampNoImage li a:visited {
                            border: none;
                        }
