I'm getting the error below but don't know what to do about it since I can't code Javascript. As I state before, IE runs this code just fine...I can't figure out why Firefox won't let it run. This cascading menu .js is just what I need for a charity website I'm helping to set up. The html portion is also shown below the .js

Error: menu is undefined Source File: file:///C:/Documents%20and%20Settings/Ray/My%20Documents/ECCHS_Website/CascadeMenu.js Line: 8

Here's the code for CascadeMenu.js 

   function InitMenu()

        {

          menu.style.visibility = "hide"
          bar[i].onmouseover = new Function ("ShowMenu("+bar[i].id+")")
          var Items = menu.children
          for(var j=0; j<Items.length; j++)
            {
              var menuItem = eval(Items[j].id)
                if(menuItem.menu != null)
                   { 
                    menuItem.innerHTML += "<Span Id="+menuItem.id+"_Arrow class='Arrow'>4</Span>"
                    //var tmp = eval(menuItem.id+"_Arrow")

I found a download of Cascade Menu with files from 2001. I also found a discussion thread as of 2006 indicating problems with the script in Firefox as of that time (Menubar Script problem in FireFox [Archive - WebDeveloper.com]). The web and web browsers have changed a lot during the past decade, so you might find it more efficient to get a new menu script than to fix this old one. (It might not even work in IE9 any more...)
