Look at your wheels. Do they form an X or an O pattern? When viewed from above or below? (ex. "X from above" "O from below")

The bigger problem is the constant 0 wired into the spin input on the holonomic drive VI.

Describe in English how you want the spin controlled (what joysticks, buttons, etc.) and we may be able to help you implement it in Labview.

ok; we are trying to do regular drive forward backwards turning left turning right
then when we press button 1 it will do shifting/crabbing

Ok, your true case looks alright then. I would suggest moving the 0 into the case for clarity purposes, but this is not absolutely necessary.

It sounds like your problem is with your false case. What does your false case look like right now and what problems are you having with it? Your first post mentions that "the wheels are inverted", but I'm not sure what this means.

OK, so what is the problem you are experiencing? What does "the wheels are inverted" mean?

Are you sure that you have the correct axis wired into the correct terminal on the Arcade Drive VI?

That's the only thing I can think of. If you didn't properly invert the motors when opening the drive in Begin.VI I don't think your holonomic VI would drive and strafe properly.
