Finding Script (GetComponent)

Hello im trying to find an other script on an other GameObject. But i get an error when i try to launch the game. (the script is atatched to an PREFAB) And its called SimpelPointSystem. The error i get:
“The left-hand side of an assignment must be a variable, a property or an indexer”

	public SimpelPointSystem pointSystemScript;

	void Start ()
		SimpelPointSystem = GameObject.Find ("Main Camera").GetComponent<SimpelPointSystem> ();

According to your code, “SimplePointSystem” is a type, so you can’t assign an object instance to it. You probably want this:

 pointSystemScript = GameObject.Find(...);
