correctAnswers scope?

I copied the instructor's code line by line and my HTML keeps displaying 0 correct answers. I believe this is because the 'let correctAnswers = 0;' is defined outside of the loop which includes the 'correctAnswers++;

Any suggestions on how to correct this issue?

Hi. Same problem here. Everything seems to work, except "correctAnswers" counter in line 27 via line 38. This is my workspace - https://w.trhou.se/6onmrlr3lx

In line 32 and 33, you have

  let question = questions[i][0];
  let answer = question[i][1];

Try changing let answer = question[i][1]; to let answer = questions[i][1];

Thank you! Was looking for a code mistake but it's just a typo. Gotta be more careful.
