Adding a Pop-up Layer to a True/False Quiz with a Health Gauge

The slider steps run from 0 to 4, starting in the middle at 2.

First, since the starting point is in the middle, and going up is positive and going down is negative, I suggest the slider steps range from a negative number to a positive number, with 0 as the starting point.

Because there are 5 questions, the slider should be able to go up 5 (if the user answers every question correctly) or down 5 (if the user answers every question incorrectly). 

In other words, I'd set the slider like this: 

Also, you don't need other variables to hold different number values. The trigger condition for showy the Stormy Waters layer could just check the value of the quizGauge variable. For example:

•  if quizGauge = -3 
•  if quizGauge is between -3 and -5

It looks like the user might be able to retake the quiz. At least, that's what I assume the RESTART button on the last slide is for. If so, it needs to have a trigger that resets the variable to its midpoint. Be sure that trigger comes before the trigger that jumps to another slide.

BTW, Question 1 has a different Slide Master layout applied than the other 4 questions. I suggest you switch so they all use the same layout.
