Feedback does not show up properly

Dear Storyline experts,

 

I set up a quiz within storyline which contains individual layers on various slides. It works out with many other stories I set up that way, but that particular seems to be corrupted.

Problem: After answering a question the feedback slide does not show up. How can I route / map / fix that?

 

What I am looking for:

If answer = correct then show layer RICHTIG

If answer = incorrect then show layer FALSCH which mostly contains a link to an individual layer to supply the student with further details.

 

Any help is appreciated. I know, that there are many other FEEDBACK topics out there but none of em could help me out. I hope the german language wont be a further problem for you.

All the best.

Sascha
