Try again layer settings while using buttons

Hello everybody,

I'm creating a "try me" mode part of my E-learning module, and I'm searching for the option to use custumiezed buttons without showing the "Try Again" layer. I found the solution for the main layer with the option "Show layer Try Again when the user clicks outside", including all buttons in the case, but I can't apply the buttons from the "Captions" layer. So when I click on Captions Button in captions layer I have the "Try Again" layer launched. How can I include shapes/buttons from other layers to use my buttons ?

Thanks in advence for your help !

Regards,

Artem
