My code keeps getting errors. I need to see a screenshot https://teamtreehouse.com/library/decomposing-our-application

function Header(props) { return ( <div className="header"> <h1>{props.title}</h1> </div> ); }

Header.propTypes = { title: React.PropTypes.string.isRequired, };

function Player(props) { return ( <div className="player"> <div className="player-name"> {props.name} </div>

   <div className="player-score">
      <div className="counter">
        <button className="counter-action decrement"> - </button>
        <div className="counter-score"> {props.score} </div>
        <button className="counter-action increment"> + </button>

); }

Player.propTypes = { name: React.PropTypes.string.isRequired, score: React.PropTypes.number.isRequired, };

function Application(props) { return ( <div className="scoreboard"> <Header title={props.title} />

     <div className="players">
    <Player name="Jim Hoskins" score={31} />
    <Player name="Bob Smith" score={33} />

Application.propTypes = { title: React.PropTypes.string, };

Application.defaultProps = { title: "Scoreboard", }

ReactDOM.render(<Application />, document.getElementById('container'));
