Condition?

Is there a condition that is for having it so the trigger does not work unless a unit is in a region.

Conditions-->
Boolean Comparasion-->
Unit-Unit in Region-->
Region X contains unit Y equal to true

Thanx to you my map can soon be done, I never use boolean so that would be my last thought

I also usually never use boolean, but then I remembered its for true/fale things, so I decided to check. It turns out it was there, so then I came here and posted it for you, then posted this message here.
