Prompt method brings up all questions and answers in one prompt.

How is this wrong when it's exactly the same as the video?

var firstQ = [ ['How many states in the US?', 50], ['What is 2 + 2?', 4], ['What month is it?', 12] ]; var correctAnswers = 0; var question; var answer; var response; var html;

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

for (var i = 0; i < firstQ.length; i += 1){ question = firstQ[i][0]; answer = firstQ[i][1]; response = parseInt(prompt(firstQ)); if (response === answer){ correctAnswers += 1; } } html = "You got " + correctAnswers + " question(s) right."; print(html);

You are prompting firstQ, the array of questions, when you should be prompting question.

This:

response = parseInt(prompt(firstQ));

should be:

response = parseInt(prompt(question));
