Subject: Re: Accessing an instance variable in another method

perhaps something like this..

NOT TESTED.. at work.. just pseudo code to get you started and give you 
ideas.. not responsible for absolutely anything including but not 
limited to your computer blowing up from running the code below.

class QuizController < ApplicationController

  def index
    @quizes=Quiz.find(:all,:limit=>5) # TODO shake this up with a random 
to get unique quizes each time
  end

  def report
    @report = "If you aren't using ruby, you failed!"
  end

  def checkanswer
    @quiz = Quiz.find(params[:quiz_id]) # get the quiz from the response 
form
    answers = @quiz.answers
    responses = params[:responses]  # get the responses from the 
response form
    @correct_answer_count = answers.zip(responses).map(0) {|sum, a, r| a 
== r ? sum + 1 : sum}
    @percentage = (@correct_answer_count / 
@quiz_completed.questions.size) * 100
  end

  end

Congrats on getting busy with rails, you are doing great and keep going!
