error help (Javascript)

hello! Im getting the following errors in a script of mine,

Its a way point script if that means anything,

Heres the code- var timer:int = 0;

var player :GameObject ;

var maxRange :int = 0;

function Start () {

}

function Update () {

timer++;

if (timer == 100)

{

 timer = 0;

 if (gameObject.tag  == "waypoint")

         {

     if (Vector3 .Distance (player .transform.position ,transform.position ) > maxRange )

             {

                 gameObject.tag  = "illegal";

             }

         }

     else if (gameObject.tag  == "illegal")

         {

             if (Vector3 .Distance (player .transform.position ,transform.position ) < maxRange )

                 {

                     gameObject.tag  = "waypoint";

                 }

         }
