Saving Highscore with PlayerPrefs not working

I am trying to save a highscore so every time i restart the game the high score stays the same unless it's beaten. The code I have currently doesn't save a highscore.

Here is my code so far:

 if (count > best)
             {
                 PlayerPrefs.SetInt("best", best);
             }
           
             if(best > count)
             {
                 best = PlayerPrefs.GetInt("best");
             }
