Get Text from an Input Field on one scene and use it as a text on another scene Unity c#

So I have a script where I get text from an input field and when I start the game the text appears in the game as a "NickName" feature. I have almost gotten it but there is one thing left to my knowledge that i need to fix. Here is my script:

using UnityEngine; using System.Collections; using UnityEngine.UI;

public class PlayerName : MonoBehaviour { public string Name;

 public Transform Nick;
 public GameObject name1;

 public Transform SaveData;
 public Transform Canvas;

 public Button start;
 public bool IsInGame = false;
  void Start ()
 {
     DontDestroyOnLoad(SaveData);
     DontDestroyOnLoad(Canvas);
     Name = Nick.GetComponent<InputField>().text; 
   

 }
 
 
  void Update ()
 {
  

     Name = Nick.GetComponent<InputField>().text;
    if(IsInGame == true)
     {
         Debug.LogError("You are in a game");
         name1 = transform.Find("NickName").gameObject;
         
         name1.GetComponent<Text>().text = Name;

         if (transform.Find("NickName") != null)
         {
             Debug.Log("The Editor has found the object 'Nickname'.");
            
         }
         else 
         {
             Debug.LogError("The editor cannot find the object 'Nickname'.");
         }
         
     }
    if(IsInGame == false)
     {
         Debug.LogError("you are not in a game");
     }
 }
 

}

(IsInGame is true when my Script StartGame script is activated)

my problem inlies that it cannot find the transform NickName. I get a nullReferenceExeption error and the LogError to catch if the transform is null does not appear in the Console.

Thank You for helping me!
