# Oksman :
Try '==' instead of just '=' might be it.
However how do you count the zombies? If they're in the same faction or something you can use the count command.
There is an implemented variable that returns amount of infected units.
Added 2 hours 6 minutes later:
Tried == as condition:
myvariable1 == 0;
but at the beginning of the mission trigger is activated straight away, even if I know the value is not 0;
No idea how to do this.
