Why are floats not accessing my inputted values?

I’m trying to make my players location change upon entering a trigger. However, the “public floats” I’ve made don’t seem to be working correctly. If I enter the collider, I get sent to (0, 0 ,0).

using UnityEngine;
using System.Collections;

public class PlayerSwitch : MonoBehaviour {

public Camera myCamera;
public GameObject myPlayer;
public float one, two, three;

void Start () 
{
	GameObject myPlayer = GetComponent<GameObject> ();
}

void OnTriggerStay (Collider other)
{
	if (Input.GetKeyDown(KeyCode.F))
	{
		myPlayer.transform.position = new Vector3(one, two, three);
	}
}

}

When I run this line of code in one of my scripts after declaring a public variable for it never actually Initializes the gameobject.

void Start () 
 {
     GameObject myPlayer = GetComponent<GameObject> ();
 }

try initializing it like this and see what happens,

void Start () 
 {
     myPlayer = this.gameobject;
}

What I don’t get is if this is your problem then why aren’t you getting a nullReferenceException?

I tested the floats up above and it all worked fine for me once the myPlayer variable was properly assigned
