Ruby Ruby Loops Build a Simple Contact List Part 3: Printing The Contact List

simpleContact.rb:37:in `block in <main>': undefined method `each' for 21:Fixnum (NoMethodError)

I tried to run the code but encoutered the following error, i compared my code with teacher's note but still can't figure out the problem

simpleContact.rb:37:in block in <main>': undefined methodeach' for 21:Fixnum (NoMethodError)

def ask(question, kind ="string")
  print question + " "
  answer = gets.chomp
  answer = answer.to_i if kind == "number"
  return answer
end

def add_contact
  contact = {"name" => "", "phone_numbers" => []}
  contact["name"] = ask("What's your name?")

  answer = ""

  while answer != "n"
    puts "Do you want to add a phone number? y or n"
    answer = gets.chomp
    if answer == 'y'
      contact["phone_numbers"] = ask("What's your phone number", "number")
    end
  end
  return contact
end

contact_list = []

answer = ""
while answer != 'n'
  contact_list.push(add_contact())
  answer = ask("Ask for another one? y/n")
end

puts "--------"
contact_list.each do |contact|
  puts "Name: #{contact["name"]}"

  if contact["phone_numbers"].size > 0
    contact["phone_numbers"].each do |number|
      puts "Phone: #{number}"
    end
  end
  puts "--------\n"
end

Not sure if it's the issue, but I noticed you have an array of phone numbers in your contact hash. Look in your while loop of the add_contact method:

contact["phone_numbers"] = ask("What's your phone number", "number")

It would make more sense to push the items to an array rather than setting that array as a phone number:

contact["phone_numbers"].push(ask("What's your phone number", "number"))

I hope it fixes your issue.

Thanks, I figured it out earlier today, phone_numbers is an array inside of a hash, so I should use push instead of calling ask method to add value into it.
