Variable Conditions

Unless I'm misunderstanding something, I don't think you need to evaluate the Boolean variables at all?

An alternate way would be to add an additional variable action to these Drops.

The second action would set a numeric variable to increase +1 in the correct cases.

So the Drop trigger would fire two actions, one action to set the respective boolean value PLUS a second action to set the Score variable to increase +1 (instead of == chose += in the Operator drop down) if it's a "good" drop.

This approach means you don't have to evaluate the Boolean variables at all.

I did a simple test (just one text element dropping on a target) and was able to set both variables this way.

Based on the description:

1. Prior to exercise set a numeric variable for total score to 0.
2. On the page where the boolean variables are being triggered add 2 actions
   1. an action on variable change (the variable changing being the boolean) that boolean is true then change the total score to be += and value of 1 (this adds 1 to whatever the value was)
   2. an action on variable change (the variable changing being the boolean) that boolean is false then change the total score to be -= and value of 1 (this takes away 1 from whatever the value was)
