Why does choosing the "p" option not work, when following this video, exactly as Jason does the coding?

Thank you Erik. Here is my code. Not sure why it is not working for me, when I choose the option for "p":

require "./contact"

class AddressBook attr_reader :contacts

def initialize @contacts = [] end

def run loop do puts "Address Book" puts "a: Add Contact" puts "e: Exit" puts "p: Print Address Book" puts "s: Search" print "Enter your choice: " input = gets.chomp.downcase case input when 'a' add_contact when 'p' print_contact_list when 's' print "Search term: " search = gets.chomp find_by_name(search) find_by_phone_number(search) find_by_address(search) when 'e' break end end end

def add_contact contact = Contact.new print "First name: " contact.first_name = gets.chomp print "Middle name: " contact.middle_name = gets.chomp print "Last name: " contact.last_name = gets.chomp

loop do
  puts "Add phone number or address? "
  puts "p: Add phone number"
  puts "a: Add address"
  puts "(Any other key to go back)"
  response = gets.chomp.downcase
  case response
  when 'p'
    phone = PhoneNumber.new
    print "Phone number kind (Home, Work, etc): "
    phone.kind = gets.chomp
    print "Number: "
    phone.number = gets.chomp
    contact.phone_numbers.push(phone)
  when 'a'
  address = Address.new
  print "Address Kind (Home, Work, etc): "
  address.kind = gets.chomp
  print "Address line 1: "
  address.street_1 = gets.chomp
  print "Address line 2: "
  address.street_2 = gets.chomp
  print "City: "
  address.city = gets.chomp
  print "State: "
  address.state = gets.chomp
  print "Postal Code: "
  address.postal_code = gets.chomp
  contact.addresses.push(address)
  else
    print "\n"
    break
  end
end  

contacts.push(contact)

end

def print_results(search, results) puts search results.each do |contact| puts contact.to_s('full_name') contact.print_phone_numbers contact.print_addresses puts "\n" end end

def find_by_name(name) results = [] search = name.downcase contacts.each do |contact| if contact.full_name.downcase.include?(search) results.push(contact) end end print_results("Name search results (#{search})", results) end

def find_by_phone_number(number) results = [] search = number.gsub("-", "") contacts.each do |contact| contact.phone_numbers.each do |phone_number| if phone_number.number.gsub("-", "").include?(search) results.push(contact) unless results.include?(contact) end
end
end print_results("Phone search results (#{search})", results) end

def find_by_address(query) results = [] search = query.downcase contacts.each do |contact| contact.addresses.each do |address| if address.to_s('long').downcase.include?(search) results.push(contact) unless results.include?(contact) end
end
end print_results("Address search results (#{search})", results) end

def print_contact_list puts "Contact List" contacts.each do |contact| puts contact.to_s('last_first') end end
end

address_book = AddressBook.new address_book.run
