Unity error on a nonexistent line of code

This is the error I get from my 31 lines of code: Assets/spawnTile.js(32,1): BCE0044: expecting }, found ''.

 var focus : GameObject;
 var cutoff : int;
 var tile : Transform;
 
 function Update () {
     var distance = Vector3.Distance(focus.transform.position, gameObject.transform.position);
     var self = transform.position;
     var selfX = Mathf.Floor(transform.position.x/1.5);
     var selfZ = Mathf.Floor(transform.position.z/.866);
 //    print (coord);
 //    print (Vector3(self.x + 1.5, self.z + .866));
     if (distance < cutoff){
         var checkX = selfX + 1;
         var checkZ = selfZ + 1;
         var coord : String = "x" + checkX + "z" + checkZ;
         if (!(GameObject.Find(coord + "(Clone)"))){
             tile.name = (coord);
             Instantiate (tile, self + Vector3(1.5, 0, .866), Quaternion.identity);
         }
         checkX = selfX + 1;
         checkZ = selfZ - 1;
         coord = "x" + checkX + "z" + checkZ;
         if (!(GameObject.Find(coord + "(Clone)")) && !(GameObject.Find(coord))){
             tile.name = (coord);
             Instantiate (tile, self + Vector3(1.5, 0, -.866), Quaternion.identity);
         }
     else if (distance < cutoff + 1) {
         Destroy (gameObject);
     }
 }

Well, my expected } is in place on line 31, and there is no " anywhere in sight. ?!
