Помогите, пожалуста, не работает выпадающее меню на JS.
Вот код JS:

var brname=navigator.appName, BrVer='';
if(brname.substring(0,2)=="Mi")
BrVer='E';
var timer = 0;
lastid = -1;

function show(id)
{
if(!((document.all)?document.all['menu'+id]:document.getElementById('menu'+id)))
return;
clearTimeout(timer);
if((id != lastid) && (lastid!=-1))
((document.all)?document.all['menu'+lastid]:document.getElementById('menu'+lastid)).style.visibility = 'hidden';
hideElement("SELECT", document.getElementById('menu'+lastid));
lastid = id;
((document.all)?document.all['menu'+lastid]:document.getElementById('menu'+lastid)).style.visibility = 'visible';
}

function hidden(id)
{
if(!((document.all)?document.all['menu'+id]:document.getElementById('menu'+id)))
return;
showElement("SELECT");
timer = setTimeout("if('"+id+"' == '"+lastid+"'){((document.all)?document.all['menu"+lastid+"']:document.getElementById('menu"+lastid+"')).style.visibility = 'hidden';}", 500)
}


function GetPos(el)
{
if (!el || !el.offsetParent)return false;
var res=Array()
res["left"] = el.offsetLeft;
res["top"] = el.offsetTop;
var objParent = el.offsetParent;
while (objParent.tagName.toUpperCase()!="BODY")
{
res["left"] += objParent.offsetLeft;
res["top"] += objParent.offsetTop;
objParent = objParent.offsetParent;
}
res["right"]=res["left"]+el.offsetWidth;
res["bottom"]=res["top"]+el.offsetHeight;
return res;
}

function hideElement(elName, Menu)
{
if(BrVer!='E') return;
for (i = 0; i < document.all.tags(elName).length; i++)
{
Obj = document.all.tags(elName)[i];
if(!(pMenu=GetPos(Menu)))continue;
if(!(pObj=GetPos(Obj)))continue;

if(pObj["left"]<pMenu["right"] && pMenu["left"]<pObj["right"] && pObj["top"]<pMenu["bottom"] && pMenu["top"]<pObj["bottom"])
Obj.style.visibility = "hidden";
}
}

function showElement(elName)
{
if(BrVer!='E') return;
for (i = 0; i < document.all.tags(elName).length; i++)
{
obj = document.all.tags(elName)[i];
if (!obj || !obj.offsetParent)continue;
if(obj.style.visibility=="hidden")
obj.style.visibility = "visible";
}
}

Вот код HTML:

<table border="0" cellspacing="0" cellpadding="0" style="height: 100%" width="142px">
