Can someone find out why this code wont work?!?!?!?!?!??!

var crosshairTexture : Texture2D;
var position : Rect;

function Start()
{
position = Rect( ( Screen.width - crosshairTexture.width ) /2 ( Screen.height -
crosshairTexture.height ) /2, crosshairTexture.width, crosshairTexture.height );
}

function OnGUI()
{
GUI.DrawTexture( position, crosshairTexture );
}

This throws no errors.

var crosshairTexture : Texture2D;
var position : Rect;

function Start(){
    position = Rect((Screen.width - crosshairTexture.width)/2, (Screen.height - crosshairTexture.height)/2, crosshairTexture.width, crosshairTexture.height);
}

function OnGUI(){
    GUI.DrawTexture(position, crosshairTexture);
}
