How does it come into play / how is created / added to the game? Is it a part of the HUD widget?

You’re getting the error because this variable:

Has no value. You have merely created a variable that can refer to a widget of a certain type. We still need to tell the editor which widget instance you mean. Imagine there are 3 widgets of that type created in 3 different parts of the game. How do we know which you want?
