Why isn't my quiz working with strings?

Hey Guys,

1st time I've asked a question on here so sorry if it formats bad....

I created my quiz as challenged in the previous video,. Admittedly, I haven't made it easy on myself by asking for strings as answers, but I still can't understand what I've done wrong.

When testing the below code, the answers I give are correct if I type them out all in lower case, as you would expect. However, when capitalising the first letter etc, my "toLowerCase" doesn't seem to work, and it says I got the answer wrong. E.G Question 1 - Answer : bones - CORRECT Answer: Bones - INCORRECT

I appreciate I haven't formatted the prints too well, but I'm more concerned with the JScript for now

Any advice would be awesome, apologies for the context of the questions, my 3 childhood toys were all I could think of!

Cheers, Aaron

    var correctGuesses = [];
    var incorrectGuesses = [];
    var numberCorrect = 0;
    var questions = [
      ["What is Doggy's favourite food", "bones"],
      ["What is Clowny's favourite method of transport?", "unicycle"],
      ["What is Bear's favourite activity?", "sleeping"]  
    ];

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


      for (var q=0; q < questions.length; q++){
        question = questions[q][0];
        answer = questions[q][1];
        response = prompt(question.toLowerCase);
        if (response === answer){
          numberCorrect += 1;
          correctGuesses.push(questions[q][0]);
        } else {
          incorrectGuesses.push(questions[q][0]);
        }
      }

    print('You scored: ' + numberCorrect + '<br>');
    print('The questions you got right were: ' + correctGuesses.join(', ') + '<br>');                           
    print('The questions you got wrong were: ' + incorrectGuesses.join(', ') + '<br>');

Your toLowerCase needs to be in your conditional statement rather than on the question. 

for (var q=0; q < questions.length; q++){
    question = questions[q][0];
    answer = questions[q][1];
    response = prompt(question);
    if (response.toLowerCase() === answer){
      numberCorrect += 1;
      correctGuesses.push(questions[q][0]);
    } else {
      incorrectGuesses.push(questions[q][0]);
    }
  }

I hope this helps
