Try again and Incorrect Layers not showing.

There's no need to add triggers to show the feedback layers of a graded question slide.

When Feedback is set to By Question, the Submit__ trigger automatically shows the Correct or Incorrect layer based on the user's answer. (This is the default when you insert a new question slide.)

When Attempts is set to a number >1, Storyline automatically adds a Try Again layer. The Submit__ trigger automatically shows the Try Again if the user answers incorrectly but hasn't used up their attempts. If there are no more attempts allowed after an incorrect answer, the Submit__ trigger shows the Incorrect layer.

helloatccw​ : Be sure your slide is set to show feedback, and be sure the Attempts field is set to the desired number that is >1.

If the problem persists, well, further troubleshooting is just guessing without seeing all the programming. Someone might be able to solve the issue if you upload the .story file. Here are the best practices for doing that:

• Only include slides that are related to the problem.
• Be sure objects, layers, motion paths, and variables have meaningful names.
• If there is proprietary content, replace or delete it. For example, replace proprietary text with “ipsum lorem” text.
