Box mit Javascript

[NC]

Ich bastle gerade ein verschiebare Box. Hier mal der Code:
CODE <script language="JavaScript1.2">
<!--
var ie4=document.all
var ns6=document.getElementById&&!document.all

function drag_drop(e){
if (ie4 && dragapproved){
crossobj.style.left=tempx+event.clientX-offsetx
crossobj.style.top=tempy+event.clientY-offsety
return false
}else if (ns6 && dragapproved){
crossobj.style.left=tempx+e.clientX-offsetx
crossobj.style.top=tempy+e.clientY-offsety
return false

}
}

function initializiere_drag(pop,drag,e){

crossobj=ns6? document.getElementById(pop) : document.all[pop];
var firedobj=ns6? e.target : event.srcElement;
var topelement=ns6? "HTML" : "BODY";

while (firedobj.tagName!=topelement && firedobj.id!=drag){
firedobj=ns6? firedobj.parentNode : firedobj.parentElement
}

if (firedobj.id==drag){
offsetx=ie4? event.clientX : e.clientX
offsety=ie4? event.clientY : e.clientY
tempx=parseInt(crossobj.style.left)
tempy=parseInt(crossobj.style.top)
dragapproved=true
document.onmousemove=drag_drop
}
}

document.onmouseup=new Function("dragapproved=false");

function box_weg(pop){
if (ie4||ns6){
crossobj=ns6? document.getElementById(pop) : document.all[pop];
crossobj.style.visibility="hidden";
}
}

setTimeout("box_weg('pops')",15000);
//-->
</script>

Lokal funktioniert das im IE, Firefox und Mozilla... Aber auf meine Homepage (www.emailpoint.de) funktioniert das nicht mehr. Man kann die Box nur noch im IE verschieben... Wieso?
