Score counter isn't working

#
So I followed a youtube tutorial on how to create a score counter, the counters there and everything but it won't count anything. If the actor, Pacman, eats a coin the score should go up by one and if he eats a Kirsche (cherrie) the score should go up by 2. But it just doesn't go up. Can somebody help me? Code of the counter1 class:
?

import greenfoot.*;
import java.awt.Color;
public class Counter1 extends Actor
{
  int score = 0;
  public Counter1()
  {
    setImage(new GreenfootImage("Score: " + score, 24, greenfoot.Color.WHITE, greenfoot.Color.BLACK));
  }
  public void addScore()
  {
       score++;
       updateImage();
  }
  public void updateImage()
  {
        setImage(new GreenfootImage("Score: " + score, 24, greenfoot.Color.WHITE, greenfoot.Color.BLACK));
  }
  
}
code of the actor, who eats the coins/Kirschen:

Actor Kirsche = getOneIntersectingObject (Kirsche.class);   
            if(Kirsche!=null)
            {
              World myWorld = getWorld();
              myWorld.removeObject(Kirsche);
              RoboterWelt roboterwelt = (RoboterWelt) myWorld;
              Counter1 counter1 = roboterwelt.getCounter1();
              counter1.addScore();
              counter1.addScore();
              counter1.updateImage();
            }
            Actor Coin = getOneIntersectingObject (Coin.class);
            if(Coin!=null)
            {
              World myWorld = getWorld();
              myWorld.removeObject(Coin);
              RoboterWelt roboterwelt = (RoboterWelt) myWorld;
              Counter1 counter1 = roboterwelt.getCounter1();
              counter1.addScore();
              counter1.updateImage();
The world code:

public class RoboterWelt extends World
{ 
    Counter1 counter1 = new Counter1();
    private static int zellenGroesse = 20;
    private int score = 0;}
?

public Counter1 getCounter1()
    {
        return counter1;
    }
I didn't put anythinf in the coin or Kirsche class, maybe that's the mistake? I don't know, please help me.

Remove:
?
1
import java.awt.Color;
from any and all classes. Then, you can drop 'greenfoot.' from in front of all 'Color'. Remove:
?
1
private int score;
from your RoboterWelt class. Your Counter1 object holds the score value. Show your entire RoboterWelt class for review.

Alright, I did that but it still doesn't work. I just checked and the score counter increases its score when Pacman hits a ghost for the first time. The other times he hits a ghost it doesn't go up. Anyway, heres the code for the RoboterWelt:

I do not see anywhere where the score is upped when hitting a ghost. Also, I do not see from where the hitBlauerGeist method is being called. Q: in what class is the 19-line code set just given above? and why is there a score field there when you already have one in the Counter1 class?
