Smartdashboard is Troublesome

[michaelwm]

When the code for our robot is first compiled, the SmartDashboard works and displays all the information as needed, most importantly our variable "throttle". However, as soon as we activate the robot, the entire SmartDashboard becomes blank, showing no variables and disallowing me from creating widgets.

code:

SmartDashboard.putNumber("throttle", throttle);
