Help with buttons and periodic tasks

[Crisann25]

I'm a first year coach, and had to step in and learn labview along with my freshmen. We are trying to run the shoot arm in periodic tasks and it is acting buggy. The up button (3) in teleop works fine, the down (2) button is jerky and works spontaneously. The arm also twitches if everything is idle. The triggers seem to work fine except that the output is erratic especially for joystick 2. Any help or guidance would be appreciated.
