Messages are not written on the page

Please tell me what is wrong with my code. I followed everything the teacher is doing, but yet the messages cannot be seen on the page after answering to the questions

var questions = [ ['How many states are in the United States?', 50], ['How many continents are there?', 7], ['How many legs does an insect have?', 6] ]; var correctAnswers = 0; var question; var answer; var response; var correct = []; var wrong = [];

function print(message) { var outputDiv = document.getElementById('outout'); 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 < questions.length; i += 1) { question = questions[i][0]; answer = questions[i][1]; response = prompt(question); response = parseInt(response); if (response === answer) { correctAnswers += 1; correct.push(question); } else { wrong.push(question); } }

html = "You got " + correctAnswers + " question(s) right." html += '<h2>You got these questions correct:</h2>'; html += buildList(correct); html += '<h2>You got these questions wrong:</h2>'; html += buildList(wrong); print(html);

Code

Wrap your code with 3 backticks (```) on the line before and after. If you specify the language after the first set of backticks, that'll help us with syntax highlighting.

      ```html
      <p>This is code!</p>
      ```

var questions = [ 
  ['How many states are in the United States?', 50], 
  ['How many continents are there?', 7], 
  ['How many legs does an insect have?', 6] 
]; 

var correctAnswers = 0; 
var question; 
var answer; 
var response; 
var correct = []; 
var wrong = [];

function print(message) { 
  var outputDiv = document.getElementById('outout'); 
  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 < questions.length; i += 1) { 
  question = questions[i][0]; 
  answer = questions[i][1]; 
  response = prompt(question); 
  response = parseInt(response); 
  if (response === answer) { 
    correctAnswers += 1; 
    correct.push(question); 
  } else { 
    wrong.push(question); 
  } 
}

html = "You got " + correctAnswers + " question(s) right.";
html += '<h2>You got these questions correct:</h2>'; 
html += buildList(correct); 
html += '<h2>You got these questions wrong:</h2>'; 
html += buildList(wrong); 
print(html);

Maybe just a typo, but I'm not sure. If it doesn't work, please show your html file.

var outputDiv = document.getElementById('output')
