Thanks for the quick reply...
OK, I can get this to work if all units are alive by the time they load in chopper but if any have died It wont fire the trigger so I need to check somehow if unit is alive...
I typed it like this:
p1 in acat AND p2 in acat...etc.
How would I exclude the ones that are dead so trigger will fire when whats left of the group are loaded in chopper?
Thanks.
