Hello, Im trying to make a scoring system in two parts, one that is attached to a GUIText and another that is attached to an object to be clicked in order to add up points.

This is what I currently have on the GUIText

var Counter : int = 0;

function onGUI(){
    guiText.text = "Score: "+CountingCode.score;
}

and this is what is on the object to be clicked to get points

CountingCode.js

static var Counter : int = 0;

function OnMouseDown(){
      Counter+=10;
}

When I click the afformentioned object with these scripts active nothing happens. Can someone please show me what is wrong?
