Object reference not working

Here is my code that was working yesterday and now doesn't work. I get an 0bject reference not set to the instance of an object error, but I'm sure it has the tag and everything? Any help?

 private var ray: Ray;
 
 private var rayCastHit: RaycastHit;
 
 function Update(){
 
 if(Input.GetMouseButton(0)){
 
 ray = Camera.main.ScreenPointToRay(Input.mousePosition);
 
 if(rayCastHit.collider.gameObject.tag == "playbutton"){
 
       Application.LoadLevel ("maingame");
 
    }
 
 }}

At what line is this error ? And it looks like your rayCastHit object is not initialized: don't you miss a physics.raycast() call somewhere ?

@dns a RaycastHit does not need to be initialized up front. It is a struct and will get it value from the Raycast(), but he is missing the Raycast() call. Without the Raycast(), rayCastHit is uninitialized on line 11 when it is being used.
