Problems with driving

[Wicked]

Our Teleop.vi appears to be working correctly, and our motors and PWMs are all in proper order. However, we're getting a problem when we attempt to drive.

In Arcade Drive:

When the joystick is moved left, the robot rotates to the right.
Similarly, when the joystick is moved right, the robot rotates to the left.
Driving forward and backward presents no similar problem.

In Holonomic Drive:

When the joystick is moved forward, the robot drives backward.
When the joystick is moved backward, the robot drives forward.
Crabbing left and right presents no problems.

Our Begin and Teleop VIs are in the image attached below. We've been trying different motor inversions, and so far, none of them have worked.
