Python

Trouble with classes and variables

Hey, I'm having some trouble with my code in the python track. I keep getting an error on the last line stating that the list 'questions' is undefined. I think this has something to do with where I've declared my variable.

class Quiz:
  questions = []
  answers = []  
   #so we can log a list of right/wrong on each question index

  def __init__(self):
    #generate 10 rand questions with numbers 1 to 10
    #add these to questions
    for num in range(0,10):
      type = random.randint(1,2)
      if type == 1:
        newquestion = Add(random.randint(1,10), random.randint(1,10))
      elif type == 2:
        newquestion = Multiply(random.randint(1,10), random.randint(1,10))
      questions.append(newquestion)

You need to reference self.

self.questions.append(newquestion)
