Boolean working, but not triggering show mouse cursor

I am attempting to have my mouse shown with a starting menu open, then hide the mouse when I start the game by clicking button “Start”. So far, it switches the boolean correctly and prints the correct string, but does not trigger the “show mouse cursor” to hide it when I click “Start”.
Help!! What did I do wrong? Or how can I work around this?

Hey there, you should move the Menu open is true logic to the on click event and have the false logic connected to the Add Viewport and remove that menuopen boolean all together.
