Ruby Building Web Apps with Sinatra Finishing Touches A DELETE Request

What am I doing wrong?

I'm supposed to create a DELETE route path which will delete "/signatures/:index"

As you can see with my code, I don't think I'm doing anything wrong. But I've gone through a few of these challenges now and have had to skip them because I've always been getting an error when creating my routes. Thus, I think I'm doing it wrong. Can someone please shed some light on the subject for me??

views/show.erb
<p><%= @signature %></p>

<form method="post" action="/signatures/<%= @index %>">
  <input type="hidden" name="_method" value="delete">
  <input type="submit" value="Delete This Signature"/>
</form>
guestbook.rb
require "sinatra"

def load_signature(index)
  # Code omitted for brevity
end

def save_signature(signature)
  # Code omitted for brevity
end

def update_signature(index, signature)
  # Code omitted for brevity
end

# Deletes the line at the given index and re-saves the file.
def delete_signature(index)
  lines = File.readlines("signatures.txt")
  index = index.to_i
  lines.delete_at(index)
  File.open("signatures.txt", "w") do |file|
    file.puts lines
  end
end

get "/signatures/new" do
  # Code omitted for brevity
end

get "/signatures/:index" do
  @index = params[:index]
  @signature = load_signature(@index)
  erb 'show'.to_sym
end

delete "/signatures/:index" do

end

It looks like some changes we made on the code challenge runner broke this challenge. That should now be fixed, and your code should pass up through Task 4 as-is. Sorry for the trouble!
