as far as I can tell I've replicated the code in the video exactly and nothing shows up in the browser but the title, any suggestions? (fyi i've tested and the js file is linking fine with the index file (using other Javascript code). this is the code I've written :
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('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 < 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); htm; += '<h2>You got these questions wrong:</h2>'; html += buildList(wrong); print(html);

54,967 PointsYou have two errors:
1) You declare outputDIV but then use outputDiv
2) You have htm; instead of html here:
htm; += '<h2>You got these questions wrong:</h2>';
Did you check the console?

3,244 PointsThanks Kris, I made those changes but still not working unfortunately.

3,244 PointsIt does run the question prompts for some reason (if i delete the last section) so maybe thats a clue? I cant see any mistakes here however.
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);
update : with this code the question prompts are running now but they run through twice for some reason and the answers are not displayed in the end.

html += '<h2>You got these questions correct:</h2>';
html += buildList(correct);
html += '<h2>You got these questions wrong:</h2>';
html += buildList(wrong); print(html);
I checked it in the console, you missed a semicolon after the first line. Happy Coding!

Incase its of interest to anyone, heres a a snapshot of the code that didn't work. I could find a way to analyse it with chrome dev tools when i clicked on 'console' it says there are two errors but didn't allow me to review that Javascript.
