Need help with quiz challenge

var quiz = [
  ["How presidents have there been?",44],
  ["How many states are there?",50],
  ["How many stripes are on the American Flag?",13]
var correctQuestions = [
var incorrectQuestions = [
var correctAnswers = 0;
var question;
var answer;
var response;
var html;
function print(message) {
  var outputDIV = document.getElementById("output");
  outputDIV.innerHTML = message;

function buildList(arr) {
  var listHTML = "<ol>";
  for (var i = 0;  i < arr.length; i += 1) {
    listHTML += "<li>" + arr[i] + "</li>"
  listHTML = "</ol>";
  return listHTML;  

for (var i = 0; i < quiz.length; i += 1) {
  question = quiz[i][0];
  answer = quiz[i][1];
  response = prompt(question);
  response = parseInt(response);
  if (response === answer) {
    correctAnswers += 1;
  } else {
html = "You got " + correctAnswers + " question(s) right.";
html += "<h2>You got these questions correct:</h2>";
html += buildList(correctQuestions);
html += "<h2>You got these questions wrong:</h2>"
html += buildList(incorrectQuestions);

I am doing the js quiz challenge and I am experiencing some problems. If someone could help me, that would be great. We need to prompt some questions and then see if they are correct. I have that done correctly expect it asks each question twice. Also, I need to have the questions answered correctly appear in a certain area and the questions answered incorrectly appear in a different area. If someone can help me, that would be great.

Hi, Brad. I tested your code in the browser console, and it works fine for me. The only thing is that you have

listHTML = "</ol>";

inside your buildList function, but it should be this:

listHTML += "</ol>";

so it's overwriting the variable instead of concatenating.

Yes. You were correct. Just a typo. Thanks for your help
