Problems with a very simple trigger

[Initeor]

Hi guys!

I've been trying to figure this out, but I'm really stuck.

Basically I want 1 unit of the costum unit-type "Redead" to appear in the "Graveyard" region every 15 seconds (with a special effect when it spawns, but that's unrelevant).

The problem is; I want the unit to spawn ONLY when there is less than 3 units of the same unit-type ("Redead") in the region ("Graveyard").

I thought you guys maybe could help me out a bit.

EVENT
Every 15.00 seconds of game time

CONDITIONS

ACTIONS
If (All Conditions are True) then do (Then Actions) else do (Else Actions)
 - If - Conditions
      - (Numbers of units in (Units in Graveyard <gen>)) Greater than 3
 - Then - Actions
        - Do nothing
 - Else - Actions
        - Unit - Create 1 redead for Neutral Hostile at (Random point in Graveyard <gen>) facing Deafult building degrees

Would appriciate some help, thank you!
