GetComponent() problems

So I am trying to get the size of my Collider, but it keeps giving me errors.

 #pragma strict
 
 static var CldHeadD : int[];
 static var CldLeftD : int[];
 static var CldRightD : int[];
 static var CldFeetD : int[];
 static var CldcornersD : int[];
 static var Skin : float = 0.9;
 static var Size : Vector2;
 static var tp : Vector3;
 
 function Start () {
     CldHeadD = new int[4];
     CldLeftD = new int[4];
     CldRightD = new int[4];
     CldFeetD = new int[4];
     CldcornersD = new int[4];
 }
 
 function FixedUpdate () {
     tp = transform.position;
     Size = this.GetComponent<BoxCollider2D>().size;
     for (var XU : int = 0; XU <= CldHeadD.length; XU++){ /*aray length*/
         var HitUp = Physics2D.Raycast(Vector2(/*pos.x*/tp.x + (XU - (Size.x * 0.5)) * Skin/*pos.x*/, /*pos.y*/  tp.y + (Size.y * 0.5) * Skin/*pos.y*/), Vector2.up);
         CldHeadD[XU] = HitUp.distance;/*Set distance*/
         print(CldHeadD);
     }
 }

and I get these errors.
