How do I change the font size...

Hi. No matter what I do the GUI Skin, I cannot change the size of the font. I have tried changing fonts and even removing the GUI skin…nothing, the font always stays the same size (and yes, I am changing the number in the “Label” section of the skin editor). What am I doing wrong?

var Score : float;
var myGUI : GUISkin;

function OnGUI (){ = myGUI;
    GUI.Label (Rect (Screen.width/2+(Screen.height/2.17),Screen.height/21.3, Screen.height/02.5, Screen.height/8),Score.ToString("000000"));

On iOS you need to import the font resources at all of the different sizes that you want in Unity 3 (Unity 4 removes this limitation).
