Action Controller: Nil Object

I am getting this error message, although I have checked the
show.rhtml file and the corresponding controller file, when trying to
look at my new permalink.  Any advice/help would be appreciated.
Thanks!

Re: Action Controller: Nil Object

Um, @story is nil.

You''ll have to post the controller code for any help.

Re: Action Controller: Nil Object

I''ve been back tracking all my work.  Now I am getting a Routing Error
looking like this: Routing Error

no route found to match "/story/new/show/my-shiny-weblog" with
{:method=>:get}

And my controller looks like this:

class StoryController < ApplicationController
  def index
    @story = Story.find(:first, :order => ''RAND()'')
  end

  def new
    @story = Story.new(params[:story])
    if request.post? and @story.save
      flash[:notice] = ''Story submission succeeded''
      redirect_to :action => ''index''
    end
  end

  def show
    @story = Story.find_by_permalink(params[:permalink])
  end
end
