I have two questions.

1) Have you tried debugging the code to make sure that mov is what you expect when you call the MecanumDrive_Cartesian() function?

2) Why are you calling MecanumDrive_Cartesian()? You don't have a mecanum (or 45-degree omniwheel) drivebase. Since you're passing a constant 0 as the first argument, it seems to me that it would be more reasonable to call an ArcadeDrive function.
