I’ve run into an issue where when I attempt to add some points to my score I get the following error:

```auto
/Users/mark/Desktop/dice-game.js:39
        score = this.score + points;
              ^

    ReferenceError: score is not defined
        at Player.addToScore (/Users/mark/Desktop/dice-game.js:39:15)
        at rollDice (/Users/mark/Desktop/dice-game.js:14:16)
        at Object.<anonymous> (/Users/mark/Desktop/dice-game.js:50:17)
        at Module._compile (internal/modules/cjs/loader.js:776:30)

        at Function.Module.runMain (internal/modules/cjs/loader.js:829:12)
        at startup (internal/bootstrap/node.js:283:19)

```

This occurs when I attempt to call the function to add 10 points `player.addToScore(10);`. The code for my player can be found below:

```auto
class Player{
    constructor (name) {
        this.name = name;
        this.score = 0;
    }
  
    addToScore(points) {
        score = this.score + points;
    }

    getScore() {
        return this.score;
    };
}
```
