Variables with Mutiple Drop objects/Targets

I confess, I am new to using variables.

I am trying to build an interaction that has 7 droppable objects and two target zones/objects.  user has to drop the two correct objects on each of the target objects to get the solution correct.

I want it to do the following:

Show a "Correct" every time they drop the right object on the right target

Show a "Wrong" every time they drop the wrong object on a target.

Show a "You got them all" when they get both the right objects on both targets (and no wrong objects).

I started with a [objectname]DropCorrect and [objectname]DropWrong (Boolean)for each object and a AllCorrect (Boolean) but cant figure out how to trigger the all correct to true.
