document.write wont print

var counter = 0;
var conclusion;
var userGuess;
var answer;



var QuestionAndAnswer = [ 
["What is the capital of Great Britain?" , "London"],
["Which member left the boyband One Direction to pursue a solo career?" , "Zayn Malik"],
["What team won the Premier League in the 2016-17 season?" , "Chelsea"]
]


for (i = 0; i < QuestionAndAnswer.length; i+=1) { 
  QuestionAndAnswers  = QuestionAndAnswer [i] [0];
  answer = QuestionAndAnswer [i] [1];
  userGuess = prompt(QuestionAndAnswers);
  userguess = userGuess.toLowerCase();

  if (userGuess === answer) {
  correct +=1;
  }
}

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

html = "You got" + correct + "right!.";

print(html);

The code will not print how many answers i get right!. where am i going wrong? I have looked over the video code and mine for the print() and as far as i can see, i am doing the same thing

I am super demotivated by this course and feel like i cant go anywhere. Any other resources or something to help me out?

This code increments a variable named "correct" when the given answer matches, and also uses "correct" to print the final result, but no variable by that name was ever established.

I'd guess you meant to put "var correct = 0;" up near the beginning of the program.
