I really appreciate both of your replies, but making the corrections you suggested has led me to another problem.

class RobotDemo : public SimpleRobot
{
	RobotDrive myRobot; // robot drive system
	Gamepad controller;
	AxisCamera& camera;
	
public:
	RobotDemo(void):
		myRobot(10, 9, 2, 1),	
		controller(1)
	{                                     <-------------------------ERROR HERE
		GetWatchdog().SetExpiration(0.1);
	
		camera = AxisCamera::GetInstance();  <--------ERROR HERE

The first error says "uninitialized reference". How do I initialize it?
The second error gets me back to where I started. It says "error within this context".

This feels like one step forward then two steps back. Thanks for your help.
