How do I root UI canvas GameObject

I feel like I am getting close to finishing this script . I need to carry over the text in the next scene. I gotten and error. I am thinking I need to declare transform. I gotten this Error CS0246: The type or namespace name `transform' could not be found . I just need to fixed this script . I am also accessing the script the score script from this test. I wondering do I also need to change anything in this script. I've change the operators on the test script . It didn't change anything.

 using UnityEngine;
 using System.Collections;
 using UnityEngine.UI;
 using UnityEngine.SceneManagement;
 public class Test : MonoBehaviour {
 private MyClockScript myClock;
 public GameObject Score;
 public GameObject Text;
 private ScoreManagerScript scoremanager;
     void Awake () {
         myClock = GetComponent<MyClockScript>();
         scoremanager = GetComponent<ScoreManagerScript>();
         Score = GameObject.Find("Tip");
         
     }
     
 
     void Update () 
     {
         if (myClock.m_leftTime <= 0 && 0 <= ScoreManagerScript.score)
 
         {
 
             SceneManager.LoadScene("new");
 
         }
 
 
 }
 
 
 }

Here is my script :

 using UnityEngine;
 using System.Collections;
 using UnityEngine.UI;
 using UnityEngine.SceneManagement;
 public class MyClockScript : MonoBehaviour
   {
       public transform GameObject;
       public int  Minutes = 0;
       public int  Seconds = 0;
   
       private Text    m_text;
       public float   m_leftTime;
   
       public void Awake()
       {
           m_text = GetComponent<Text>();
           m_leftTime = GetInitialTime();
           DontDestroyOnLoad (RootCanvas.transform.root);
 
       
       }
   
       public void Update()
       {
           if (m_leftTime > 0f)
           {
               //  Update countdown clock
               m_leftTime -= Time.deltaTime;
               Minutes = GetLeftMinutes();
               Seconds = GetLeftSeconds();
 
               //  Show current clock
               if (m_leftTime > 0f)
               {
                   m_text.text = "Time : " + Minutes + ":" + Seconds.ToString("00");
 
               }
               else
               {
                   //  The countdown clock has finished
                   m_text.text = "Time : 0:00";
               }
           }
       }
   
       private float GetInitialTime()
       {
           return Minutes * 60f + Seconds;
       }
   
       private int GetLeftMinutes()
       {
           return Mathf.FloorToInt(m_leftTime / 60f);
       }
   
       private int GetLeftSeconds()
       {
           return Mathf.FloorToInt(m_leftTime % 60f);
       }
   }
