Javascript quiz not working

I'm following this tutorial to build the quiz but when i type in the correct answers into the prompt. The end results says i got 0 questions right.

    var questions = [
    ["what is my name?", "Callum"],
    ["How old am I?", "20"],
    ["Where do I live?", "UK"]
                ];
    var correctAnswers = 0;
    var question;
    var answer;
    var response;
    var html;

    function print(message) {
    document.write(message);
    }

    for(var i = 0; i < questions.length; i +=1)
    {
      question = questions[i][0];
      answer = question[i][1];
      response = prompt(question);
      if(response === answer)
      {
        correctAnswers += 1;
       }

       }

    html = "You got " + correctAnswers + " questions correct";
    print(html);

Hi Callum Singh,

You have this line inside the loop:

answer = question[i][1];

The array's name is questions (with an 's'). So this should be:

answer = questions[i][1];
