Menu sjusk

Har fået stykket et script sammen flere forskellige steder fra, som jeg havde tænkt mig som udgangspunkt for en menu.

Systemet virker tilsyneladende meget godt, men ved "MouseOver" på Gruppe+nr, placerer "popuppen" sig efter musens placering.

Hvorledes ændres dette, så popup-boxen holder samme afstand til venstre skærmkant.
Det er formodentlig noget med:
position:absolute; left: 200;
Men hvor sætter jeg det ind ???

<style>
