Prerequisite triggers that allow other triggers to be activated

I have come across a problem in my map i'm making. I want some soldiers to be able to radio in artillery on a key location. But i dont want them to be able to  activate the radio until they get into the right position. So to sum up my problem, how would i make a trigger that would allow another trigger to be activated?

Make a trigger and put this in its activation field NAME_IN_FUP = 1 and then make the trigger you want to be activated and put this in its condition field NAME_IN_FUP == 1

I have recently discovered the power of synchronization right in the mission editor.  It will have the same effect you are looking for if done properly.
