Pneumatics Problem

[tmk]

Our test robot has a double action solenoid on it. I wanted button 3 on the right joystick to make it go both out and in. But currently, button 3 is making it go out and button 4 is making it go in. (Even though button 4 is not wired to the solenoid.) In fact, I completely deleted button 4 from the program, and it still controlled the solenoid. Buttons that don't exist in the program shouldn't work when I run it! I also tried creating an imaginary motor (one that doesn't exist on the robot) for button 4 to control, just to give it something to do, but it still controls the solenoid.
Any help is very, very welcome.
