Help with Code

[nlt5]

Thanks to all on this sight for the guidance offered to all teams. We are working hard trying to figure out how to write code and we need some help. below is the code we have written so far. What we want to have happen is for our drive system to be arcade and we are using the left joystick on our xbox controller and we have two shooter motors. Ideally I would like to have the shooter motors turn on and off with one button but I am not sure how to write that so I attempted to start the motors with the press of one button and turn them off with another button. So far nothing works. The drive motors turn in opposite directions, so I attempted to invert the motors. This allowed us to drive forward and reverse but we could not turn. I am not concerned with autonomous at this time just teleop. I would appreciate any insight into problems with this code and suggestions on how to make it work. Thank you in advance. (sorry i'm not sure the best way to attache my code.)
