Traffic Light State Machine Dictionary Issues

If someone could assist I was building my State Machine for my college class and for some reason I ran into an issue with creating my dictionary for each colored light in my scene. Here is what it looks like.

	//State in which the bulb turns green
	enum BulbGreen
	{
		ON,
		OFF,

		NUM_STATES
	}
	//State in which the bulb turns yellow
	enum BulbYellow
	{
		ON,
		OFF,

		NUM_STATES
	}
	//State in which the bulb turns red
	enum BulbRed
	{
		ON,
		OFF,

		NUM_STATES
	}
	//Keeping track of Current Bulb Color State
	private BulbGreen curStateGreen = BulbGreen.ON;
	private BulbYellow curStateYellow = BulbYellow.ON;
	private BulbRed curStateRed = BulbRed.ON;

	private Dictionary<curStateGreen, Action> gsm = new Dictionary<curStateGreen, Action> ();
	private Dictionary<curStateYellow, Action> ysm = new Dictionary<curStateYellow, Action> ();
	private Dictionary<curStateRed, Action> rsm = new Dictionary<curStateRed, Action>();

The private Dictionary curStateGreen, Yellow, and Red come up with an error stating.

Assets/LaPinska_Brandon_Lab1/TrafficLightStateMachine.cs(44,28): error CS0118: TrafficLightStateMachine.curStateRed' is a field’ but a `type’ was expected

I also have to set up a timer on these lights to circulate from green to yellow to red back to green. If anyone can help I would greatly appreciate it.

If you cant help with this or know where to find out to allow me to learn why this is an issue I would also appreciate that as well.

Thank You fellow Unity3d’ers!

Confused by why you use 3 different enums that are identical: why not just have “enum LightState”?

Regarding the Error: When you define which generic version of the dictionary you want to use, you must specify an actual TYPE or class into the < TParameter > , rather than a variable.

So

private Dictionary<curStateGreen, Action> gsm; 

is an invalid declaration, but

private Dictionary<BulbGreen , Action> gsm;

Would be a valid declaration

I am new to dictionaries and how many enums I am actually supposed to have. The practice that they had us doing was just a light that turns on and off. I was just trying to piece things together. Thanks for the help.
