What is wrong with my android code?

public class NewGame extends Activity implements OnClickListener{
    EditText word;
    Button createGame;

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.newgame);

        word = (EditText) findViewById(R.id.word);
        createGame = (Button) findViewById(R.id.createGame);
        createGame.setOnClickListener(this);

    }

    public void onClick(View v){
        Intent i = new Intent(NewGame.this, Game.class);
        i.putExtra("word", word.getText().toString());
        startActivity(i);
    }
}
