DHTML navigation menu

[shadowheart]

I'm trying to make a simple text-based menu that expands similarly to how folders expand in windows explorer. I've tried 2 different ways to achieve this, and both works flawlessly in IE and Opera. However, in Firefox (and Mozilla too I would guess since they were both made by Mozilla), the submenus refuses to expand. I'm out of clues now and I'm desperate for some help. I need the script to work on as many different browsers as I can.

The script is as follows:

<!-- Hide script from older browsers
// Open the menu specified by 'currMenu'
function toggleMenu(currMenu)
{
var thisMenu;
var thisPic = eval("document.menu" + currMenu + "p");
var menuOffsets = new Array(88, 124, 52, 52); // => 12 * Rader + 4 <=> Rader * 10 + (Rader + 2) * 2
var openMenus = new Array(0, 0, 0, 0);
var menu2o;
var menu3o;
var menu4o;
var menu5o;

if(document.all)
{
thisMenu = eval("document.all.menu" + currMenu + "content.style");
menu2o = eval("document.all.menu2.style");
menu3o = eval("document.all.menu3.style");
menu4o = eval("document.all.menu4.style");
menu5o = eval("document.all.menu5.style");
}
else if(document.getElementById)
{
thisMenu = eval("document.getElementById('menu" + currMenu + "content')");
menu2o = eval("document.getElementById('menu2')");
menu3o = eval("document.getElementById('menu3')");
menu4o = eval("document.getElementById('menu4')");
menu5o = eval("document.getElementById('menu5')");
}
else
{
thisMenu = eval("document.menu" + currMenu + "content");
menu2o = eval("document.menu2");
menu3o = eval("document.menu3");
menu4o = eval("document.menu4");
menu5o = eval("document.menu5");
}

if(thisMenu.display == "block")
{
thisMenu.display = "none";
thisPic.src = "images/plus.gif";
openMenus[currMenu-1] = 0;
}
else
{
thisMenu.display = "block";
thisPic.src = "images/minus.gif";
openMenus[currMenu-1] = 1;
}

menu2o.top = 32 + menuOffsets[0]*openMenus[0];
menu3o.top = 44 + menuOffsets[0]*openMenus[0] + menuOffsets[1]*openMenus[1];
menu4o.top = 56 + menuOffsets[0]*openMenus[0] + menuOffsets[1]*openMenus[1] + menuOffsets[2]*openMenus[2];
menu5o.top = 68 + menuOffsets[0]*openMenus[0] + menuOffsets[1]*openMenus[1] + menuOffsets[2]*openMenus[2] + menuOffsets[3]*openMenus[3];
}
// Stop hiding script -->

In Firefox the images will change correctly, but the submenus will not appear (the .display = "block" part) and the last bit where the top properties of the menus are changed doesn't work either. The Firefox JavaScript Console finds no errors in the script

Nevermind, I fixed it myself
