Some help please on setting an advanced condition on a trigger

[dutch]

Hi all,

I am currently working a a PVP concept and will be using area triggers for win / end mission situations.
What i am trying to do set the relative trigger in a way that it requires multiple conditions to activate. This i know how to do. The problem now is, the conditions i'm aiming at are a bit advanced, at least for me. What im trying to do is have the trigger activate if its area holds:

- 3 vehicles (lets say m1a1)
- which are still mobile and able to fire
- with at least 2 crewmen class players aboard each tank
- players are to be alive
- all these conditons must be met for 5 minutes

So basicaly the trigger needs all these above conditions met, to be activated.

Could someone give me the relative code, to put into the condition field?

Regards,

Dutch
