How to make a connection from a widget to a BP object?

Well. You create 2 Huds that overlap one another. Don’t. Even if you hide one text, the other HUD still shows it.

if you have 2 players, each will create a unique interface - I guess that’s not what you want. Create it elsewhere - in the Player Controller, or in the Game Mode - these singletons are as easy to access.

Essentially, ensure the UI is created only once if that’s what you want.
