Chief Delphi - Code problems

Hi Everyone,
if someone has time can you please take a look at our code. When we compile this the driver station shows no robot code. Currently we are only trying to use the drivetrain41 and the shootermotors. The other code is written so that we can test those items when they are ready. Do I need to comment them out when they are not connected? For example the servos are not plugged into the rio yet will that cause a problem?

Thank you very much
Code:
