Main menu navigation with game pad

Hello, everyone. I tried to make main menu navigation with the gamepad. I used an event tick and a sequence to connect my nodes to the event and then I defined a variable and checked the condition button pressed and in true, I increased the variable quantity.the next step I checked another condition to prevent the variable to go upper 3 and below 1. finally, I used a switch on integer and subsequently I used functions like open level for going to the game level and visibility for showing the Options box and etc. my problem appears when I want to set a navigation for options box. I don’t know why it doesn’t function. I’d appreciate with a little aid.
