My solution is essentially the same as that in the Solution video, however, my counter is only telling me I'm getting 1 correct, not 3. Can someone tell me why?
var questions = [ ["Where are you from? ", " Ohio"], [" Who is your wife? ", "Ngoc"], [" How many kids do you have ", 2]]; var correctAnswers = 0; var question; var answer; var response;
function print(message) { document.write(message); }
for (var i = 0; i < questions.length; i++) { question = questions[i][0]; answer = questions[i][1]; response = parseInt(prompt(question));
if (response === answer) {
correctAnswers += 1;
}
}
print(correctAnswers);

Also be aware that for the first answer you have " Ohio", so even a string comparison would fail unless you included the space in the response.

And happy coding!
