ok, sorry, a little clearer..
I have a situation when a sound message will be played if any member of my group is in a vehicle...
I put this situation in a script and I had to write as much conditions as many group member I have...
So I tought there is a more simple way to gather these conditions to one condition, if I got the expression which tells 'any member of the group'
You know there are so many expressions similar, like 'leader Group01', or 'foreach units Group01'...actually foreach means EVERY not ANY...
