Problem with Vector3 position.

Hi, I'm having a problem getting the right position from an object. I am still new to Vector3 and am confused as to why the closed position is different from the position of my object. This script should slide the door open on-click to the specified coordinates of 'open'. I believe that it should work except that the 'closed' variable receives completely different parameters than what the position says. Any help would be highly appreciated, thank you!

 #pragma strict
 // Check if door is open or closed
 var isOpen : boolean;
 // Variables for open and closed position values
 var closed : Vector3;
 var open : Vector3;
 
 var endPoint : Vector3;
 var duration : float = 1.0;
 
 private var startPoint : Vector3;
 private var startTime : float;
 
 function Awake (){
     
 }
 
 function Start () {
     isOpen = false;
     closed = transform.position;
     startPoint = closed;
     endPoint = closed;
     startTime = Time.time;
 }
 
 function Update () {
     
     transform.position = Vector3.Lerp(startPoint, endPoint, (Time.time - startTime) / duration);
 }
 
 function OnMouseOver (){
     if (Input.GetMouseButtonDown(0)){
         if (isOpen == false){
             startPoint = closed;
             endPoint = open;
             isOpen = true;
         }
         else {
             startPoint = open;
             endPoint = closed;
             isOpen = false;
         }
     }
 }
