hvorfor virker mit script kun i firefox ikke i explorer

altså jeg har følgende >


  var so = new VLCObject("myVLC", "300", "200", "0.8.6");
  so.write("vlccontents");


Hvor 300 og 200 er størelsen
så kunne jeg godt tænke mig at få størelsen fra det her >


if (document.all) {
  browserwidth  = document.body.clientWidth - 9;
  browserheight = document.body.clientHeight -18;               
} else {
  browserwidth  = window.innerWidth - 9;
  browserheight = window.innerHeight - 18;     
}
screenheight = screen.height
screenwidth  = screen.width


Derfor har jeg så gjort sådan her >

  var so = new VLCObject("myVLC", ""+browserwidth+"", ""+browserheight+"", "0.8.6");
  so.write("vlccontents");


og det virker fint i firefox, vlc kommer til at fylde hele browser vinduet som den skal
Men i explorer virker det ikke
den skriver at argumentet er ugyldigt.
jeg tror at der går noget galt i den tilhørende js fil
sikkert noget i den del der sørger for at VLC ikke blokeres i explorer, js filen ser sådan her ud >
