Ruby Post HTML challenge

Hey there, I have been trying to solve this but keep getting bumped. Can't seem to clear the redirect portion that will redisplay. Hope a kind soul is able to help me out. Thanks!

views/new.erb 
<p>Please enter your name below.</p>

<form method="post" action="/signatures/create">
  <input type="text" name="signature">
  <input type="submit">


  </form>
guestbook.rb 
require "sinatra"
require "uri"

# Appends the signature to the file as a new line.
def save_signature(signature)
  File.open("signatures.txt", "a") do |file|
    file.puts signature
  end
end

get "/signatures/new" do
  erb :new
end


# ADD CODE TO RECEIVE FORM SUBMISSIONS HERE
post "/signatures/create" do
  save_signature (params["signature"])
  redirect "/#{params["signatures/new"]}"
end

Your goal is to redirect the user back to the form to enter another signature, after their signature is created. The way this app is set up, anytime a user's browser loads the path "/signatures/new", that form will be displayed.

So the code redirect "/#{params["signatures/new"]}" is not going to do what you want; there's no need to use a parameter here. Instead, you can simply redirect "/signatures/new".
