Correct answers are not counted.

I followed along with the video multiple times and keep running into the same problem. Even when I type the correct answers to the quiz, it always says I got "0 correct answers".

var array = [
  ['What is the color of the sky?', 'blue'],
  ['What is your name?', 'bob'],
  ['What day is it?', 'friday']
];

var i;
var correctAnswers = 0;
var question;
var answer;
var response;
var html;

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


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

html = "You got " + correctAnswers + " question(s) right.";
print(html);

Hi Zach, ".toLowerCase" is a method, meaning you're missing the "()" at the end. Try this adding them like this: "response = response.toLowerCase();

It should solve your problem :)
