Leader board Getting no error but not showing scores

Hi im making an quiz game and in the end of the game i saving the player name with the score. i dont have any idea how to make scoreboard so i follow this tutorial in youtube https://www.youtube.com/watch?v=U7p3wZsX7RY&t=1821s. i dont have an error but the score and name doesnt show when game run. I am modifying the string[] Scoreformat to save the value score from the gamecontroller scrip. Can anyone show an example line that can call and add into the list the score value inside the public void savescore and getscore. Thank you for future help.

     //saving scores in gamecontroller script
           public void Endround()
             {
                 isRoundActive = false;
                 dataCOntrollerT.SubmitNewplayerScore(playerScore);
                 endRoundScoretext.text = dataCOntrollerT.GetHIghestplayerScore().ToString();
         
         
                 FinalScore = playerScore;
                 PlayerPrefs.SetInt("FINAL_SCORE", FinalScore);
                 PlayerPrefs.Save();
         
         
                 questionDisplay.SetActive(false);
                 ROundendDisplay.SetActive(true);
             }
