redirect

Why doesn't this work?: redirect("/#params{['signatures/new']}")

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"

# 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
post"/signatures/create" do
  save_signature (params["signature"])
  redirect("/#params{['signatures/new']}")
end

post "/signatures/create" do
  save_signature(params[:signature])
  redirect("/signatures/new")
end

Your new.erb is correct, what isn't correct however is how you're referencing the signature an how you're trying to redirect.

To get the signaturre from the form it must be params[:signature], To redirect you need to reference the path which means like the post do "/signatures/create" but instead of create its new so "/signature/new", if you have any questions please let me know :)
