heres my code: (to big to upload)


var questions:Array = new Array(["What is as big as you are and yet does not weigh anything? ", "shadow"], ["You can hold it without using your hands or arms. What is it? ", "breath"], ["What gets wetter and wetter the more it dries?", "towel"]);//quesion array

};
function nextround() {
 attempts = 0;
 result_txt.text = "";
 if (round<questions.length+1) {
  question_txt.text = "Riddle "+round+": "+questions[round-1][0];
 } else {
  question_txt.text = "Game Over!";
  gameOver = true;
  check_btn.inner_txt.text = "Play Again";
 }
}
function gameInit() {
 check_btn.inner_txt.text = "Check";
 gameOver = false;
 score = 0;
 round = 1;
shuffle(questions);;
 nextround();
 score_txt.text = "Points: "+score;
}

   }
  }
 } else {
  gameInit();
 }
};
