Save Empire Earth

Hello guys need some tips

I created a spawner of grenadiers, I put a rally point all works but the spawner never stops doing units.
I tried to put a condition with pop cap etc... Like Obama said in tuto
But the problem is still..

What' is needed on the trigger box
I put a condition then do nothing like Obama said just put a condition and you are done...

Thx

if population is =< ( USE A NUMBER )
create (at spawn) then set stance attack/move ( to ralley

idk what your doing but if all your doing is making grens then that will be the only condition and effects yourll need
