I managed to get it working in the end (I never realised there was a .zip file right at the bottom of the page with all the necesarry files in!!)

But now I have a different problem, see here:

All the animations work and the links to the approriate pages display in the status bar, but clicking them doesn't do anything. Im guessing it's something to do with the z-axis in the css? I could be wrong though, here is the css for the navigation:

        .lavaLampWithImage {
            position: relative;
            overflow: hidden;
            padding-left:20px;
        }
                .lavaLampWithImage li {
                    float: left;
                    list-style: none;
                }
                    .lavaLampWithImage li.back {
                        background:url(../../image/navHoverRight.png) no-repeat right bottom;
                        width: 15px;
                        z-index: 8;
                        position: absolute;
                    }
                        .lavaLampWithImage li.back .left {
                            background:url(../../image/navHoverLeft.png) no-repeat left bottom;
                            height: 30px;
                            margin-right: 9px; /* 7px is the width of the rounded shape */
                        }
                    .lavaLampWithImage li a {
                        text-decoration: none;
                        color: #FFF;
                        text-align: center;
                        z-index: 10;
                        float: left;
                        position: relative;
                        overflow: hidden;
                        margin: auto 5px;
                        padding:10px 5px 30px;  
                    }
                        .lavaLampWithImage li a:hover, .lavaLampWithImage li a:active, .lavaLampWithImage li a:visited {
                            border: none;
                        }

Thanks to anyone who can help!

I'm 99% sure that your problem is with the z-index. If you have any elements with a z-index higher (or above) the links, then the links will deactivate. Or seem to, at any rate. Try to eliminate any unnecessary z-index properties and try to give all the links a similar level.

Also, why did you put this in the JavaScript section and not the CSS section?
