Unexpected Token BCE0043?

I need some help to fix this in my javascript, i think i got everything right but it just gives me this error:

" Assets/GameSetup.js(17,112): BCE0043: Unexpected token: ). "

This is my code:

 #pragma strict

  var mainCam : Camera;

  var topWall : BoxCollider2D;
  var bottomWall : BoxCollider2D;
  var leftWall : BoxCollider2D;
  var rightWall : BoxCollider2D;

  var Player01 : Transform;
  var Player02 : Transform;

  function Update () {

		//Move each wall to it's edge location:

		topWall.size = new Vector2 (mainCam.ScreenToWorldPoint (new Vector3 (Screen.width * 2f, 0f, 0f,)).x,) 1f;
		topWall.Center = new Vector2 (0f, mainCam.ScreenToWorldPoint (new Vector3  ( 0f, Screen.height, 0f)).y + 0.5f);
		
}

this line:

topWall.size = new Vector2 (mainCam.ScreenToWorldPoint (new Vector3 (Screen.width * 2f, 0f, 0f,)).x,) 1f;

should probably look like:

topWall.size = new Vector2 (mainCam.ScreenToWorldPoint (new Vector3 (Screen.width * 2f, 0f, 0f)).x, 1f);
