UserInputService not working on key press or any user input?

function onInputBegan(input,gameProcessed)
    print("okwtf")
    if input.Type == Enum.UserInputType.Keyboard then
        print("xd")
        if input.KeyCode == Enum.KeyCode.X then
            print("xpress")
        end
    end
end


UserInputService.InputBegan:Connect(onInputBegan)

Nothing is printed, I am very confused
