Are you talking about the Knowledge Check slides? Sorry, but text in an image cannot be translated by Jive: Einblenden is that 'Show'? Are you using the embedded Failure captions? I just double-checked in 9.0.0.230:
- I created a Knowledge Check Slide
- I changed attempts to 2 and Failure message to 2 (default is None)
- I had two failure messages on the slide, and changed the text of the first message
- I tested and the first message popped up when my first attempt was incorrect
You have to be as careful with knowledge check slides as with the normal question slides: do not delete embedded objects (those without a separate timeline). I see that you apply simple actions for Success and After Last attempt. The action After Last Attempt will not be executed when the first attempt is unsuccessful.
You can have my answer translated using the Translate button at the bottom right. Although I understand some German, don't dare to write in German.
