weird drive problems

[samknight213]

We have had this problem for about a week and a half, so when we drive forward its fine. When we turn left while driving forward, it's fine same as the right. When spinning left and right it is also fine. But the problem comes when we drive backwards. Driving backwards straight is fine, but when we turn left on the joystick the robot turns back right and vice versa. Does anybody have a clue what is happening in the code. We have tried making a case structure in teleOp.vi to see if the y axis is positive or negative then inverse it if it is negative but we may have done it wrong so if you could show a picture of how it should look. Thanks....

But who knows I've been blaming wiring because that's what I do when I don't know something.
