I feel like the task doesn't explicitly state what they mean by a 'contact' local variable in the block.

Anyway, my code is below, can someone please tell me the issues i must fix?

Thanks

contact_list.rb 
contact_list = [
  {"name" => "Jason", "phone_number" => "123"},
  {"name" => "Nick", "phone_number" => "456"}
]

contact_list.each do |contacts|
  contacts.push(contacts)
end

contact["name"].each do |name|
  puts "Name: #{name}"
  contact["phone_number"].each do |phone_number|
    puts "Phone Number: #{phone_number}"
  end
end

Hi Philip,

In this case, it means to use |contact| when you are doing contact_list.each. It's basically saying "for EACH contact, name it 'contact'". So, at that point, you can use the below to pull the values from each contact:

contact['name']
contact['phone_number']

You have the right idea, but you're doing more than needed. All you need is the .each block, and not the tons of code below it. To get you started:

contact_list.each do |contact|
  puts 'Contact Name: ' + contact['name']
  # now 'puts' your phone_number on this line
end

The "local variable" is whatever you choose to name it within the |contact| pipes after 'do'

If you want to keep using string interpolation like you are currently doing with #{}, you can:

puts "Contact Name: #{contact['name']}"

Good luck!

Mike
