Translating a script from JS to Boo, need help. (Short script)

Ok the JS version of this script works, while the Boo version does not. I get an error in Unity.
JS:

var P;
function Start(){
	P=new Stats();
	}
function OnGUI(){
	if(P.HP<0) P.HP=0;
	if(P.Player){
		GUI.Label(new Rect(10,10,30,20),"Health: "+Mathf.Round(P.HP)+"%");
		}
	}
//Boo Version below
import UnityEngine
import System.Collections
class Creation(MonoBehaviour): 
	P
	def Start ():
		P=Stats()
	def OnGUI():
		if(P.HP<0): P.HP=0
		if(P.Player):
			GUI.Label(Rect(10,10,30,20),"Health: ${Mathf.Round(P.HP)}%")

Here are all the errors for the Boo version:
Assets/Code/Boo Creation.boo(6,11): BCE0005: Unknown identifier: ‘Stats’.
Assets/Code/Boo Creation.boo(8,14): BCE0019: ‘HP’ is not a member of ‘object’.
Assets/Code/Boo Creation.boo(9,14): BCE0019: ‘Player’ is not a member of ‘object’.

Can someone show me the correct translation so I’ll know for future reference?

Stats() refers to Stats.js, a javascript file, is that a problem? Can boo not access variables/classes from it?

I read that entire page and I don’t see how that answers my question. Everything there seemed unrelated. I’ve read that page before anyway.

You skipped over my main question which is asking how to make the actual code work.

Read section 4 on that page again; it explicitly answers your question that I quoted. Nothing else is going to work until you do that.

Ok I think I get it…So if I want to make it easier on myself, I should use one language for the entire game…So I don’t have to worry about doing what that article says…

It’s trivial to create a Standard Assets folder and move the scripts with the function you want to call there.

True, you should have little problems putting the scripts in the right place. In general though, if it’s not back-breaking, you are better off having your scripts in one language (both for bi-directional communication between them and for your own sanity).
