help sending non static variable to a singleton

Im trying to access a non static variable score with the code below. using UnityEngine; using System.Collections;

 public class Score : MonoBehaviour { 
     
     public int score = 0;
     
     void Start()
     {
 
     }
     
     void Update()
     {
         ShowScore();
     }
 
     void ShowScore()
     {
         string timeString;
         
         timeString = score.ToString();
         GetComponent<GUIText>().text = timeString;
     }
     
 }

and give the information to the singleton.

public static class Leaderboard { public const int EntryCount = 10;

 public struct ScoreEntry {
     public string name;
     public int score;
     
     public ScoreEntry(string name, int score) {
         this.name = name;
         this.score = score;
     }
 }
 
 private static List<ScoreEntry> s_Entries;
 
 private static List<ScoreEntry> Entries {
     get {
         if (s_Entries == null) {
             s_Entries = new List<ScoreEntry>();
             LoadScores();
         }
         return s_Entries;
     }
 }
 
 private const string PlayerPrefsBaseKey = "leaderboard";
 
 private static void SortScores() {
     s_Entries.Sort((a, b) => b.score.CompareTo(a.score));
 }
 
 private static void LoadScores() {
     s_Entries.Clear();
     
     for (int i = 0; i < EntryCount; ++i) {
         ScoreEntry entry;
         entry.name = PlayerPrefs.GetString(PlayerPrefsBaseKey + "[" + i + "].name", "");
         entry.score = PlayerPrefs.GetInt(PlayerPrefsBaseKey + "[" + i + "].score", 0);
         s_Entries.Add(entry);
     }
     
     SortScores();
 }
 
 private static void SaveScores() {
     for (int i = 0; i < EntryCount; ++i) {
         var entry = s_Entries[i];
         PlayerPrefs.SetString(PlayerPrefsBaseKey + "[" + i + "].name", entry.name);
         PlayerPrefs.SetInt(PlayerPrefsBaseKey + "[" + i + "].score", entry.score);
     }
 }
 
 public static ScoreEntry GetEntry(int index) {
     return Entries[index];
 }
 
 public static void Record(string name, int score) {
     Entries.Add(new ScoreEntry(name, score));
     SortScores();
     Entries.RemoveAt(Entries.Count - 1);
     SaveScores();
 }

}
