count squad member condition

[forzajuve 20]

{_x in thislist} count units gAlpha == 2 

have this is as condition of trigger to count when squad is reduced to 2 but it's not working. help?

[color="#FF0000"]([/color]{alive _x} count units gAlpha == 2[color="#FF0000"])[/color];

This is what I use. The trigger doesn't need a radius and should be set to none
