Get variable values from a blueprint to another one

Hello,

I wanted to create a minigame on unreal engine like an escape game !

I have two qcm widget that set a value named “reussi” to true if the answer is correct. The problem is that i want to access this from an other blueprint but i struggle.


Explain what those 2 blueprints are (both are widgets?), where they are and how they come into play.
