[Unsolved] Trigger Help

I need help making a trigger:
When the game starts, I want to remove all nonplaying units. Meaning: If a color slot is not taken, I would like to remove all pre-placed units and buildings that are under the control of the player.

Ok I have no idea why this is off topic. . .

Moved to World Editor Help Zone.

Basically, on event map init, you loop though all players and remove thir units if thier slot status (a condition) is equal to not playing.

It's deadly easy ...

Events

Map initialization

Conditions
Actions

For each (Integer A) from 1 to 12, do (Actions)

Loop - Actions

If ((((Player((Integer A))) slot status) Equal to Has left the game) or (((Player((Integer A))) slot status) Equal to Is unused)) then do (Unit Group - Pick every unit in (Units in (Playable map area) owned by (Player((Integer A)))) and do (Unit - Remove (Picked unit) from the game)) else do (Do nothing)

Ribenamania, That leaks 1 unit group for evey player that is missing.

XD ..yea
