Prompting with 2 dimensional arrays.

I wrote this code without using 2 dimensional arrays and it works but after trying again with 2-D arrays I have a problem. It says theres a problem in line 10 (where my prompt is) but that part of the code runs fine when previewed.

var questions = [
  ["What's my first name?","Danilo"],
  ["What's my middle name?","Armand"],
  ["What's my last name?", "Rodriguez"]
]
var correctAnswers;
var wrongAnswers;

  for (var i = 0; i < 4; i += 1){
  var answer = prompt(questions[i][0]);
    if (answer === questions[i][1]) {
      correnctAnswers +=1} else {wrongAnswers +=1}
  }

document.write("You answered " + correctAnswers + " correctly and " + wrongAnswers + " incorrectly.")

Hi Danilo, when you look at your correct answers counter after the if conditionals, there is a typo correnctAnswers should be correctAnswers
