Mecanum drive problems

We have been programming our robot in regards to driving, but are having problems getting all of our expected results. We are programming with the holonomic.vi and are controlling the robot with a 3-axis Logitech Extreme 3D Pro Joystick. As of right now, we are able to move forward, backwards, left, right, and in both a CW and CCW rotation. Our problems come in when we try to execute a left/right slide. Following is a list of how our robot acts in regards to joystick input:

Forward: All wheels forward
***Desired motion
Backward: All wheels backwards
***Desired motion
Left: No activity
***Would like to slide left
Right: No activity
***Would like to slide right
CCW turn: Robot turns CW
***Opposite of desired motion
CW turn: Robot turns CCW
***Opposite of desired motion

If anyone has any ideas on how we could fix this problem to allow our robot to slide, we would GREATLY appriciate it. In addition, if anyone has an idea of how to fix our inversion of our CW and CCW turns, that would be wonderful as well!!
