How to call the "erb" method within the route block? I have brain fog atm.

Challenge task 3 of 4!

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
  @index = params[:index]
  @signature = load_signature(@index)
end
views/edit.erb 
<p>Please enter your name below.</p>

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

I tend to forget the Sinatra syntax when I switch to other web frameworks. Fortunately the syntax is super simple!

I think the syntax you are looking for is this:

get "/:index/edit" do
  # YOUR CODE HERE
  @index = params['index']
  @signature = load_signature(@index)
  erb :edit
end
