Casting between widgets in order to get variables, Object Wildcard?

I am currently trying to make a small game, mostly just to learn more about using Unreal Engine, and ran into an issue in my widgets. I have one for my main menu and another for my HUD. I have a variable in my Main Menu which the user enters through a text box. I want to display this variable on my HUD. I cast to the main menu, got all of that working. However, I do not understand what to do with the object wild card pin? It sounds like a simple problem that I just am being stupid about. Any help would be appreciated, here is a picture of my cast:
