switch between objects and keep last position

Scripting
1

i want made a switch between a first and third person gameobjects, and keep the last unique position…can i do this?
i have this:

var first : GameObject;
var third : GameObject;

var playerpos1 : Vector3 = first.transform.position;
var playerpos3 : Vector3 = third.transform.position;


function Update ()
{

if(Input.GetKeyDown(KeyCode.C))
{

if (first.activeSelf == true)
{
third.SetActive(true);
third.transform.position = playerpos1;
first.SetActive(false);
}
else
{
third.SetActive(false);
first.transform.position = playerpos3;
first.SetActive(true);
}
}
}

You need to cache the transform component (a reference) and not the position (a Vector3 value)

var playerpos1 : Transform = first.transform;
//stuff
third.transform.position = playerpos1.position;

I pull a few hours testing and I could not. I am very noob and not find a way.

var first : GameObject;
var third : GameObject;
var playerpos1 : Transform = first.transform;
var playerpos3 : Transform = third.transform;

function Update () {

if(Input.GetButtonDown("camview")){
if (first.activeSelf == true){
third.SetActive(true);
third.transform.position = playerpos1.position;
first.SetActive(false);
}
else{
first.SetActive(true);
first.transform.position = playerpos3.position;
third.SetActive(false);
}
}
}

and this is the fail result, before and after switch
