Thanks - that works! Good tip about the quotes/doubles, etc.
One thing though, they all see me right away now, and I only want this trigger to fire when someone goes down. I guessed that this bit:
east_area1_total = +thislist; east_area1 = thislist
was adding 1 to the count in thisList (?) and took the plus off, but then it failed. So I set the second trigger to repeat, but that doesn't help.
How can I set it so that it checks the units against the total units and fires the 'warn everybody' trigger only when someone is shot? (Gawd, I'm still having trouble with the basics).
