how do i Count Each Sprite with a certain animation?

Hi! i wonder how do i count a sprite with a specific animation, for example:

for every Sprite playing "X" animation, add 100 to "X variable"

Doesn't it work to do it like this? Everytime that animation ends for every copy of that sprite 100 gets added to points. By making it a trigger the points will only be added once everytime the trigger is triggered

Trigger....

System Pick all Sprite

Sprite is animation"X" playing......................Add Sprite.PickedCount*100 to variable X

korbaach, it works but its goes on an on, its creates a loop. there is a way just to make like 1 shot?

EDIT: i added "trigger once", it works now, thanks a lot guys!!
