Adding to vars and deleteing a gameobject

Question

I am making a game where the player has to pick up chemicals and craft them. How would I make a script that would, on collision, delete the gameobject, and add to a global var?

This is what I have (includes the crafting script)

on the player

 static var onumber : int = 10;
 static var hnumber : int = 10;
 var water : int = 10;
 var HP : int = 10;      //HP stands for Hydrogen Peroxide
 
   
 function Update(){
   if(Input.GetKeyDown(KeyCode.Z)){
     if(onumber > 0){
       if(hnumber > 1){
         onumber -= 1;
         hnumber -= 2;
         water += 1;
       }
     }
   }
 
   if(Input.GetKeyDown(KeyCode.X)){
     if(onumber > 1){
       if(hnumber > 1){
         onumber -= 2;
         hnumber -= 2;
         HP += 1;
       }
     }
   }
 
   if(Input.GetKeyDown(KeyCode.I)){
     onumber += 1;
   }
 
   if(Input.GetKeyDown(KeyCode.O)){
     hnumber += 1;
   }
 }

and on the chemical (dropped)

 static var onumber;
 
 function OnCollisionEnter(collision : Collision) {
   if(collision.gameObject.tag == "Player"){
     onumber += 1;
     Destroy(collision.gameObject);
   }
 }

what did I do wrong?

-Thanks, this is REALLY urgent!!!! I need this done by tomorrow!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

The easiest way to create a global var is to create a script and add it to an object somewhere, call it GameMaster or something like that and GIVE IT ITS OWN TAG. Put all your global variables in that script, then when you access it it will be persistent across the level.

To access it from any other script you can use

 gameMaster = GameObject.FindGameObjectsWithTag("GameMaster"); //link to the game master

 gameMaster.GetComponent(GameMasterScript).onumber += 1; //alter the global variable

Thats what I do anyway.

you need to send a message to the script counting the onumber, including the onumber. use the find function to get the object with the script, then sendmessage with filler like ("collision, onumber). then in the main script, have a function collision (integer){ onumber += integer; } use script reference to get the find and sendmessage commands.
