Try again layer not moving to Incorrect Layer after set amount of failed attempts

BettiSalmieri : You're doing way more work than you need to. And that's probably what's causing problems.

You can designate how many attempts to allow for a question slide.

When Attempts >1, Storyline automatically adds a "Try Again" layer. The "Try Again" button on that layer just has a trigger that closes the layer (like RonPrice mentioned). 

The program will automatically show the "Try Again" layer when the user answers incorrectly but hasn't used up their attempts. 

If the user reaches the attempt limit and still answers incorrectly, the program will automatically show the "Incorrect" layer. 

In other words, you don't need to track attempts with a variable, nor add triggers for which layer to show. Just let Storyline do what it's programmed to do.
