Choose which GUItext to display

Hi, it's me again.

So I've got a treasure chest. Several of them, actually, and all of them contain different amounts of gold. Decided to make a script where I could enter how much gold in the inspector. I also have a script attached that displays a GUItext when you open the chest, giving the amount of gold you just earned. However, it appears to my eyes that the GUItext is actually combining the amounts from ALL the chests with that script. (so that it always overlap the amount of gold - kir in this game - from ALL the chests with that script attached) Am wondering if anyone knows a solution to that. Bonus round: I'm sure there's a way to combine the scripts, but every time I try to run OnGui from within the openchest script, I never trigger the GUI, so good on ya if you're able to help this noob figure out how to do this in one script. Thanks, and God bless.

Script 1: Chest open

 var    chestSound : AudioClip; //chest opening sound clip goes here
 var treasureChest : GameObject; //treasure chest prefab goes here
 var moneyinchest : int;
 
 
  
 // function Start(){
  //if(PlayerPrefs.GetInt("Opened Chest", 0) == 1){
  //Destroy(gameObject);
 // }
 // }
  
 function OnTriggerEnter (col : Collider) {
 //PlayerPrefs.SetInt("Opened Chest", 1);
 if(col.gameObject.tag == "Player") { //checks to see that our character controller with tag "Player" has entered the trigger
 Playermoney.curMoney += moneyinchest;
 openmoneychestgui.openchest = true;
 AudioSource.PlayClipAtPoint(chestSound, transform.position); //plays our soundclip at position of collider/trigger
 treasureChest.animation.Play(); //plays the default animation applied to our treasureChest model
 Destroy(gameObject);// destroys the gameobject that has this script, so our collider in this case
  
  
 }
 }

Script 2: Display GUI

 static var openchest:Boolean=false;
 var moneybox : GameObject;
 var chestopenmoneyScript : chestopenmoney;
 
 
 //function Start (){
 //chestopenmoneyScript = moneybox.GetComponent("chestopenmoney");
 //}
 
 
 function OnGUI () {
      
      
      if(openchest == true) 
      if(GUI.Button(Rect(800,700,400,175),"You found" +   chestopenmoneyScript.moneyinchest +   "kir!"));{
      
       }
     }
     
     function Update () {
     if(Input.GetButtonDown("Action"))
      openchest = false;
      }
