Code not running

Can someone help find the error in my code? The prompt boxes aren't appearing. Thanks.

var questions =[
  ["How many states in the United States?" , 50],
  ["How many continents are there?"] , 7],
  ["How many legs does an insect have?" , 6]
];
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));
}

Hi Andrew, you simply have an unexpected ']' in your questions array, all you need to do is remove it and the code should work! :)

var questions =[
  ["How many states in the United States?" , 50],
  ["How many continents are there?" , 7], //removed extra [ from this line
  ["How many legs does an insect have?" , 6]
];
