It really does matter where the code is. Context means a lot when trying to determine what might be going on in a real time system.

For example, if it's in a parallel task outside the Robot Main event loop, and if it is not in a sequence enforced by the "error out" connection from Begin.vi, the Refnum Get for your left encoder might be getting executed before the Refnum Set for the encoder has been done.
