How to not count click on help layer as an attempt in a test mode exercice

Hi, Maxime, and welcome to E-Learning Heroes! ✨

Thank you for sharing what you're trying to accomplish!

I'm looking forward to what our talented community members will suggest for your specific scenario, but here's what I'd recommend:

• Create a layer for your instructions button (we'll call it Info_button). 
• On your base layer, add a trigger to show the Info_button layer when the timeline starts.

• On your Info_button layer, add a trigger to show the Information layer when the button is clicked.
• For the layer properties, check the option to hide other slide layers in your Info_button layer, but uncheck it in your Information layer. 

I am attaching a sample .story file. 

Let me know if this works!
