How do i create a score system?

Heres my script that has GUI:
static var PlayerMoney = 10;

    function Start() {
    
    }
    
    function OnGUI () 
    {
      GUI.Button(Rect(50,40,60,60), "10");
    }

Heres my Collect sciprt

#pragma strict

function Start () {

}

function OnTriggerEnter (Col : Collider) 
{
  PlayersMoney.PlayerMoney += 10;
  Destroy(Col.gameObject);
}

How do i make the gui.button + the collect sciprt?

I mean not debug.log but gui.button.

GUI.Button(Rect(50,40,60,60), “Score:” + PlayerMoney);
