Can someone help me ?

What is wrong with my code? Thank you so much :)

var correctAnswer = 0;

var questions = [
  ['what is the capital of sweden', 'stokholm'],
  ['What is my favorite TV show', 'COMMUNITY'],
  ['What is my favorite movie', 'Love Actually'],
];

var answer;


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


function askQuestions( quiz ) {
  for ( var i = 0; i < quiz.length; i += 1) {

     answer = prompt(quiz[i][0]);
     answer = answer.toLowerCase();

        if (answer == quiz[i][1]){
           correctAnswer+=1;
          print( 'That is correct ');
         } else {
            print( 'sorry '); 
            }
   }

}


askQuestions(questions);


document.write("<p>You got " + correctAnswer + " out of 3 questions correct.</p>")

:x: message is a function argument. Those don't need to be defined.

:point_right: You didn't describe your problem, but I do notice one functional issue:

It looks like you're converting the user's answer to lower case, but then comparing it to stored answers which contain upper case characters. Only answers stored as lower case can match a correct answer.

Happy coding!   -sp:sparkles:
