Problem in vertical menu

You need to declare String array in following way

var menuids = ["verticalmenu", "verticalmenu1"];

ya sry its declared the same way still giving errors

if i use

var menuids = new Array("verticalmenu", "verticalmenu1")

i get

Microsoft JScript runtime error: 'document.getElementById(...)' is null or not an object

How can you expect it to work when you do it wrong way.

I already gave you correct way

Microsoft JScript runtime error: 'document.getElementById(...)' is null or not an object

var menuids = ["verticalmenu", "verticalmenu1"];

var submenuoffset = -2 //Offset of submenus from main menu. Default is -2 pixels.

function createcssmenu() {
    for (var i = 0; i < menuids.length; i++) {
        var ultags = document.getElementById(menuids[i]).getElementsByTagName("ul")
        for (var t = 0; t < ultags.length; t++) {
            var spanref = document.createElement("span")
            spanref.className = "arrowdiv"
            spanref.innerHTML = "&nbsp;&nbsp;"
            ultags[t].parentNode.getElementsByTagName("a")[0].appendChild(spanref)
            ultags[t].parentNode.onmouseover = function() {
                this.getElementsByTagName("ul")[0].style.left = this.parentNode.offsetWidth + submenuoffset + "px"
                this.getElementsByTagName("ul")[0].style.display = "block"
            }
            ultags[t].parentNode.onmouseout = function() {
                this.getElementsByTagName("ul")[0].style.display = "none"
            }
        }
    }
}
