[Blueprints] Prototype Menu System

I need help with something, so I set up another menu(I’m making an rpg this is an inventory menu), I made a gamestate for it, I set it up in the game instance class, I copied some of the code for the pause menu to pause when opening it, I replaced the referencing to the pausemenu with my inventory menu and it doesn’t work, I pressed the button I set up(tab) and nothing happens, am I missing something?
