Ruby Building Web Apps with Sinatra Updating Data An Edit Form

Having trouble assigning the value of a method to an instance variable- Task 2 of 4- Building apps with Sinatra

Not sure what I'm doing wrong with this one. Can't seem to figure out how to assign the value of the load_signature() method to my @signature instance variable.

guestbook.rb 
require "sinatra"

# Loads the signature at the given line index.
def load_signature(index)
  lines = File.readlines("signatures.txt")
  # Parameter is a string; convert to integer
  index = index.to_i
  lines[index]
end

get "/:index/edit" do
  # YOUR CODE HERE
  load_signature(@index) 
  @signature = load_signature()
  @index = (params["index"])
end
views/edit.erb 
<p>Please enter your name below.</p>

<form>
  <input type="text" name="signature" value="<%= %>">
  <input type="submit">
</form>

The problem is in lines 13 and 14:

  load_signature(@index) 
  @signature = load_signature()

On line 14, your method needs an object as a parameter, but you forgot to write it.

If you just want the right answer, let me know! :)
