Motors/solenoids won't work; Can't print to console

[FRC3220]

I don't know what to do. I'm out of ideas. I go to a small, rural high school, that doesn't offer any programming classes, so I've taught myself some coding over the past few months. My code looks fine, and I can't find any mistakes in it, but for whatever reason, nothing on the robot (other than driving) will work. None of the solenoids extend, none of the window motors turn...nothing. I've nested a few print statements throughout my code, but they aren't printing to the console when the robot is running. Can someone take a look at my code, and tell me if there are any glaring mistakes? I know it's a lot to ask, but I don't have any other options at this point. Thank you all so much in advance. (By the way, our robot has a pneumatic-powered arm, sort of like a tractor backhoe or excavator. The arm rotates on a window motor. It also shoots by pushing the ball with a solenoid into 2 spinning motors.)
