Taken a step further, different controllers use different axis in different places. For instance, an Xbox controller is quite different than a Logitech gamepad in which axis are assigned where.

I suspect that whichever controller you are using does not have the layout of joystick axis in the manner that the code expects.

As Alan said, you need to determine which axis is activated in code when you move the joysticks, then assign them correctly to your VI's in begin.
