error in code (Please help)

I have a error in my way point script, Two infact (I made one of them accidentily)

The script- #pragma strict

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";

                     }

             }

                 

 }

{

}

The errors

-waypoint.js(66,2): UCE0001 ':'expected. Insert a semicolon at the end. -waypoint.js(67,1): BCE0044: expecting }. found".

 function Update(){
 if(Vector3.Distance(player.transform.position,transform.position ) < maxRange && gameObject.tag == "illegal")
 gameObject.tag = "waypoint";
 else if(Vector3.Distance(player.transform.position,transform.position ) > maxRange && gameObject.tag == "waypoint")
 gameObject.tag = "illegal";
 }
