How to Enable Jquery Lavalamp's Links

I've used lavalamp's menu in my project several times and have experienced the same problem 2 or 3 times after copying the code from the downloadable zipped file. It's as if the links were not there and even you click the menulink the page will not redirect. The culprit is the default javascript code from the zipped file:

$("#nav").lavaLamp({
            fx: "backout",
            speed: 700,
            click: function (event, menuItem) {
                return false;
            }
        });

The "click" function should return true, or delete the function if you won't implement your own code on click.
