My player component score is not changing

My player component score is not changing. it is fixed as when i set it at the counter component level . please see my code below

function Header(props) {
  console.log(props)
  return (
    <header>
      <h1>{props.title}</h1>
      <span className="stats">Player:{props.totalPoints}</span>
    </header>
  );
}

const Player = (props) => {
  return (
    <div className="player">
      <span className="player-name">
        {props.name}
      </span>
      <Counter score={99} />
    </div>
  );
}

const Counter = (props) => {
  return (
    <div className="counter">
      <button className="counter-action decrement"> - </button>
      <span className="counter-score">{props.score}</span>
      <button className="counter-action increment"> +</button>
    </div>
  );
}

const App = () => {
  return (
    <div className="scoreboard">
      <Header title="Scoreboard" totalPoints={0} />

      {/*Players list */}
      <Player name="Uchechukwu Onuekwusi" score={999} />
      <Player name="Uchechukwu Onuekwusi" />
      <Player name="Uchechukwu Onuekwusi" />
    </div>

  );
}

ReactDOM.render(
  <App />,
  document.getElementById("root")
)

Mod Edit: Fixed code formatting to be more readable. See comment below for how to do this.

When posting code, there is some markdown you can use to make it more readable. If you wrap your code in three back-ticks you'll get special formatting, and you can optionally add the language for fancy syntax highlighting.

```language

<Player name="Uchechukwu Onuekwusi" score={999} />
<Counter score={99} />

Looks like you're hard-coding scores.
