No prompt on the quiz!

Using Safari browser for the course but I can't seem to get it to work. Right now I don't even get a prompt when I preview the code and I can't understand why. Any help will be greatly appreciated.

var questions = [
  ['What is the Lone Star state?', 'texas'],
  ['What is the Sunshine state?', 'florida'],
  ['Where is the Big Apple?', 'new york']
];
var correctAnswers = 0;
var rightAnswer = [];
var wrongAnswer = [];
var message = '';
var answer;

for( var i = 0; i < questions.length; i++ ){
  answer = prompt(questions[i][0]);
  answer.toLowerCase();
  if( answer === questions[i][1]){
    rightAnswer.push(questions[i][0]);
  }else{
    wrongAnswer.push(questions[i][0]);
  }
}
function print(message) {
  document.write(message);
}

for(var i = 0; i < rightAnswer.length; i++){
  message = '<h3>Right Answers</h3>';
  message += '<ol>';
  message += '<li>' + rightAnswer[i] + '</li>':
  message += '</ol>';
}

print(message);

Thank you

Hey Ronny,

Check out this for loop -

for(var i = 0; i < rightAnswer.length; i++){
  message = '<h3>Right Answers</h3>';
  message += '<ol>';
  message += '<li>' + rightAnswer[i] + '</li>':
  message += '</ol>';
}

You'll see that you have a colon(:) where there should be a semicolon(;) instead.

Fix that, and it should work!

Thanks for pointing that out. I changed the colon for a semicolon but I'm still not getting a prompt. I also tried the code in the Chrome console and it seems to work, so it may be a workspace issue.

Hmm, worked for me when I tried it. Try doing a ctrl+F5, I think recently workspaces are having a hard time reloading everything. I may be wrong, but it's worth a try.

Are you using a Windows machine or is that the ctrl on a Mac? I just tried the workspace in the Chrome browser and it worked.

Nice, looks like it was a cache thing. ctrl+f5 just clears the cache for that page, I imagine it works on both Windows and OSX.
