Check if variable of all objects is true

is it possible to check variable of all object instances to see if they are all true

You can check the opposite.
Assuming you check a simple yes/no var=1 or var=0
To check if all objects have var =1

If var of object = 0 / set scenevar true to 1
If var true = 0 all objects have var =1
If var true = 1 at least 1 object has var=0

I have fixed this issue i used repeat for all instances
