Trigger !alive multiple objects

[Cytreen 14]

Im trying to get my Tasks Setup correctly and need help with the 2nd trigger. Task is to destroy multiple weapon crates in a town. Upon last crate Tack set to complete.

Here is the trigger that works for 1 object;

Condition
!alive objectname;

On activation
tskDesCache setTaskState "Succeeded";

Need help with the condition field for when all multiple object die Tack is set to compleat

Condition
!alive object1, object2, object3, object4;

On activation
tskDesCache setTaskState "Succeeded";

How do you write a !alive for multiple objects and && didnt seem to work.

I tryed

!alive obj1 && obj2

But it did not work

!(alive obj1) && !(alive obj2)

OR

In each weapon crate sub trigger,

On Activation 
obj1_done=true; 

On Activation 
obj2_done=true; 

Then have a global trigger

Condition
obj1_done && obj2_done

Sweet. Thank you so much. It was bugging me all day trying to do that lol. I used the first example and it worked perfectly. The other way i will use for a global check for all task completed to end mission. Now im just down to making a task complete trigger when a officer1 and officer 2 is captured.

{alive _x} count [obj1,obj2,obj3,obj4] < 1

Got another question that i could not find in the biki. How do you make it so that a trigger only activates from a Player and not just bluefor.

{isplayer _x} count thislist > 0
