Limiting Quiz Attempts in Storyline 360

I think the problem was that the default value for the "Attempts" variable was 0. That means that the first time the user reaches the Results slide, the variable hasn't registered that as an attempt. When they click the Retry button, the variable increases to 1, but that's really their 2nd attempt at the quiz. 

The attached file limits the attempts to 2 including the first pass through the quiz. (It's only got 1 question slide and the Results slide, because I'm not gonna spend time going thru a 20-question quiz.) 

FYI: I added a "You've reached your limit" message. It would definitely need editing, but I think there should be something that tells the user the reached the attempt limit. It should also tell them how to proceed. 

I also added a text box showing the variable value. That's useful during testing, so you can see what the value is.
