Alternative version not working!?

I tried making my quiz via this route but my code does not work. Can anyone spot the reason why?

var questions = [

["Where is Arsenal from?", "London"], ["Where is Real from?", "Madrid"], ["Where is Fenerbahce from?", "Istanbul"]

];

var answer; var correctAnswer; var correct = 0;

var html;

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

alert("This quiz test your knowledge of international football clubs");

for (var i =0; i < questions.length; i+= 1) {

answer = prompt(questions[i][0]); answer = answer.toLowerCase(); correctAnswer = questons[i][1];

if (answer === correctAnswer) {

correct +=1;

}

}

html = "You got " + correct + "questions correctly!"; print(html);
