Race saving best times on different scene

Hello I want to save my best times on a different scene using the UI, so far my scripts manage to stop the time al the goal, but the best time reamains 0. These are my two scripts. Thanks!

Timer:

 using UnityEngine;
 using System.Collections;
 using UnityEngine.UI;
 
 public class Timer : MonoBehaviour {
     
     public float time = 60;
     
     public float tempTime;
     
     public Text text;
     public Goal goal;
     
     void Update(){
         
         if(goal.lap < 1){
             
             tempTime += Time.deltaTime;
             
             time = 60;
             
         } else {
             
             time = tempTime;
             
             //to scores see highScoreTracker
             
         }
         
         text.text = "TIME : " + tempTime.ToString();
         
     }
     
 }

HiScoreTracker:

 using UnityEngine;
 using System.Collections;
 using UnityEngine.UI;
 
 public class highScoreTracker : MonoBehaviour {
 
     public Timer timer;
     
     public float highScore = 15f;
     
     public Text text;
     
 
     void Start(){
         
         highScore = PlayerPrefs.GetFloat(Application.loadedLevelName);
         
         if(highScore == 0){
             
             highScore = 60;
             
             text.text = "TOP TIME : NONE";
             
         } else {
             
             ChangeText();
             
         }
         
     }
     
     void Update(){
         
         Debug.Log(highScore);
         
         if(timer.time < highScore){
             
             highScore = Mathf.Round(timer.time * 100) / 100;
             
             Save();
             
         }
         
     }
     
     public void Save(){
         
         PlayerPrefs.SetFloat(Application.loadedLevelName, highScore);
         
         PlayerPrefs.Save();
         
         print("saved");
         
         ChangeText();
         
     }
     
     public void ChangeText(){
         
         text.text = "TOP TIME : " + highScore.ToString("F2");
         
     }
     
 }
