why isn't the prompt showing up?

I've been following this code exactly and going over it with a fine tooth comb, and I can't figure out why my prompt isn't showing up.

Does anyone see something I don't? 

var questions = [
 ['how many states are in the US?', 50],
 ['how many continents are there?', 7],
 ['how many legs does a dog have?', 4] 
];

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 = questions [i][1];
 response = parseInt(prompt(question));
  if (response === answer) {
   correctAnswers +=1;
  }
}

html = "you got " + correctAnswers "question(s) correct!";
(print(html);

Hi Rachael,

It's because your last two lines both have syntax errors. Those lines should look like this:

html = "you got " + correctAnswers + /* you were missing a concat operator here*/ "question(s) correct!";
print(html); // You had an extra parenthesis here
