Please with my solution

I don't understand why my code doesn't even print out the prompt.

right = []
wrong = []

var questions_and_answers = [
  ["how many eggs?", 1],
  ["how many boys in the classroom?", 9],
  ["how many girls in the classroom?", 7]
]

for (i=0; i<questions_and_answers.length; i+=1) {
  answer = parseInt(prompt(questions_and_answers[i][0]))
  if ( answer === questions_and_answers[i][1] ) {
    right.push(questions_and_answers[i][0]);
  else {
    wrong.push(questions_and_answers[i][0]);
  }
  }
}

document.write("You got " + correct.length + " questions right")

document.write("you got these questions right")
for (i=0; i<right.length; i+=1) {
  document.write(right[i])
}

document.write("you got these questions wrong")
for (i=0; i<wrong.length; i+=1) {
  document.write(wrong[i])
}

The brace on line 16 is out of place. It should go before the "else" on line 14.

Also, on line 20 you have "correct" (which has not been defined) instead of "right".
