I use the DontDestroyOnLoad Function to preserve my score to the next level. How do i show my High score when i die, using the save score that was preserve between scenes? (If the score was more than the HighScore).

Before using the DontDestroyOnLoad Function, I used PlayerPrefs to save my score and I was able to get a high score when I died. But now my High Score is not working. How do I make my high score work properly? I really need some help right now. When I died my High Sore is displayed in a death Menu and the main menu that I created. Can someone help me in some way.
