Re: Need some help figuring out the SFX SmartDashboard

This doesn't give me a bug, but as far as I can tell, the variable is always zero. That is probably because I'm unable to change the default case. Nothing appears on the dashboard when I use that code.
We have found that SmartDashboard::GetNumber only works if you have previously used SmartDashboard:utNumber on the same key. So we just do a SmartDashboard:utNumber in the ctor of all our subsystems for whatever parameters we will need. Then in the periodic methods we can call SmartDashboard::GetNumber and it will work.

Is this a "programming error" or a "programmer error"?
