Hi Ramadan,
variables it is, then!
But first, you'll need to add another layer to your results-slide, named "Try Again" or something. You can copy&paste your existing Failed-Layer to create this new layer and add a 'Try Again'-button from the result layer's 'Design'-tab.
Now, you add a variable "LastTry" to your project (type True/False, default False).
Then, you add another trigger to the base layer of your results slide with the trigger: "Show Layer 'Try Again' WHEN timeline starts on 'this Slide' IF Quiz..ScorePoints < Variable Quiz.PassPoints AND LastTry = FALSE;
Also, add the condition 'IF LastTry = TRUE' to the result slide's base layer's already existing trigger that shows the Failed-layer.
Lastly, you add a trigger 'Change variable 'LastTry' to TRUE when timeline starts on 'this layer'' to your 'Try Again'-layer.
Unless I'm forgetting something, that should do the trick.
Regards,
Marc
