Insects don't have 30 legs — there's the problem! :smile: Just kidding.... (well, not about the insects!)

:point_right: Actually, there's a few issues here:

  • you assign your question to a variable questions (with an "s") but you prompt using question (no "s")
  • JavaScript is case sensitive. You must spell parseInt with capital "I"
  • did you want to see the result? You accumulate correctAnswers but then don't use it
