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);
     }
 }

}
