How come the the following code is not working? Please help...

function InitMainMenu() {
var obj = document.getElementById("menuBar");
var iframeMain = document.createElement("IFRAME");
iframeMain.frameBorder = 0;
iframeMain.style.width = document.body.clientWidth;
iframeMain.src = "javascript:false;";
iframeMain.style.zIndex = 5;
iframeMain.style.position = "absolute";
obj.parentNode.insertBefore(iframeMain, obj);
}
