Make a widget open a widget?

hi all, i’ve been trying to get this to work properly and since im a nub i have no idea how to do it. i have a widget i can open just fine but i’d like to open a sub-widget somehow and it never works; it only ends up calling 1 widget. can anyone help me out please? it’s obvious i’m doing something wrong…

i’ve looked into it and i know a game instance isn’t what i want (that will be for the settings menu)

can anyone help?
