Victors in reverse not responding.

[RoboTigers1796]

Hi there!
I'm one of the programming mentors for Team 1796 and we're encountering a problem with our Victors not responding when trying to go in reverse; the Victors respond moving forward. I've included a scaled down base code that still won't work. I know there must be something simple I'm missing...what is it??? Thanks in advance, everyone!

    public FRC2010Team1796() {
         getWatchdog().setExpiration(0.1);

         compressor.start();


    }
 
    public void operatorControl() {
        getWatchdog().setEnabled(false);

        while (isEnabled() && isOperatorControl()) {
            getWatchdog().feed();

             if (stickRight.getRawButton(4)) {

            if (stickLeft.getTrigger()) {
                     armup.set(true);
                } else {
                     armup.set(false);
                }
            if (stickLeft.getRawButton(3)) {
                     armdown.set(true);
                } else {
                     armdown.set(false);
                }
                robotDrive.arcadeDrive(stickLeft);
            }
        //}
    }
}

Thanks! We're really stuck here.

What do the LEDs on the Victors do when you command reverse?

[RoboTigers1796]

the LED's don't change (remains orange).

If button 4 is pressed but not the trigger button, then claw 1 and 2 will be set to -1 and then immediately overwritten by 0 based on the trigger button if statement.

A nested if - else if - else structure is what you need.

of course! a million thank you's!!!!!
