[LFRobotics]

I have no idea why the issue with this program escapes me. I have been looking at it for days with no headway. Maybe a new set of eyes can see the problem. The program is simple. It uses my XBox class to control a four motor arcade drive system using one of the joysticks on the controller. Some buttons then control a couple accessory motors.

Here is the code: https://github.com/FranklinMarquette/Robot2016

Here is what the driver station says when I try to enable the robot:

The whole thing compiles and uploads just fine but fails at run-time.

Thanks so much,
