Checking an objects script to change an int on another script

I was wondering how I would go about checking an objects script / coordinates so that way it would affect another scripts integers. This would be used with 21 different objects.

Something like:

 Object.js:
 
 var Cor : Position;
 
 function Update(){
 
 if(input(get.position) == Cor){
 
 get.script("Correct.js")
 intCor == +1
 
 }
 
 
 }
 
 
 
 ObjectCheck.js:
 
 
 var intCor : int = 0;
 
 function Update() {
 
 if(intCor = 21){
 level.load(nextlevel)
 }
 
 }

How would I go about doing this?
