GUI Live Counter - Accessing another script

So I'm currently trying to have a GUI element access information from a different script, and then paste that onto the screen.

Script A (Does not include GUI Text, only the data the GUI tries to access)

 using UnityEngine;
 using System.Collections;
 
 public class PlayerMovementScript : MonoBehaviour {
     public float Speed = 2.0f;
     public int Lives = 3;
     public GameObject Player;
     public int NumberOfShipsAlive = 1;
     
     void FixedUpdate()
     {
         if (Input.GetKey(KeyCode.D))
         {
             transform.position += transform.forward * Speed * Time.deltaTime;
         }
         if (Input.GetKey(KeyCode.A))
         {
             transform.position -= transform.forward * Speed * Time.deltaTime;
         }
         if (Input.GetKey(KeyCode.R))
         {
             if (NumberOfShipsAlive == 0)
             {
                 GameObject spawnPlayer = (GameObject)Instantiate (Player);
                 NumberOfShipsAlive += 1;
             }
             else
             {
                 return;
             }
         }
     }
     void OnTriggerEnter()
     {
         Destroy(this.gameObject);
         Lives -= 1;
         NumberOfShipsAlive -= 1;
     }
 }

Script B (Includes GUI) using UnityEngine; using System.Collections;

 public class GUIScript : MonoBehaviour {
     public GameObject numberOfLives;
     public GUIText LiveCounter;
 
     // Use this for initialization
     void Start ()
     {
         GameObject numberOfLives = GameObject.Find ("numberOfLives");
         PlayerMovementScript playerMovementScript = numberOfLives.GetComponent<PlayerMovementScript>();
         LiveCounter.text = numberOfLives.ToString ();
     }
 }
