suggestions for a trigger

[hurlothrumbo]

I have a situation in my map.  Its a multiplayer coop map.  At one point the squad needs to get into a vehicle and then, once they are all in, a trigger goes off and an obstruction is removed.
Problem is, because its multiplayer, there could be somone disconnects or is being stupid.  So they might not get in.  Equally though, I cant have it as a radio trigger accessible to all because someone will call the radio early and ...bad things will happen.
So is there a way to have a radio trigger that only the group leader can use?

or any other suggestions on how to handle this situation?

what u shld do is Group the trigger with the leader. This shld only allow the leader to activate the trigger. Not having OFP handy on this comp right now i cant help u that much!
