Toggling speed

[Robodragons4630]

I am trying to think of a way to toggle speed. What I am looking to do is make it so that I can choose a speed and then from that I have 5 seconds to move the joystick. While I am moving the joystick the case structure cant just go false. When the joystick isn't moving the case will be false and you have 5 seconds to move the joystick again before it goes false and you have to choose a speed again. I have a picture attached that shows my current vi.
