I get an error, but not sure what I'm doing wrong!

Hey guys,

It's quite an easy task I have to do, but I seem to make a mistake and I can't figure out what that is...

Thanks in advance!

Cheers, Ferre

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

contact_list.each do |contact|
  puts contact_list["name"]
  puts contact_list["phone_number"]
end

Oh this is the task btw: Using the each method, iterate over the contact_list array. Assign each array item to the local variable contact in the block and print out the value of the name and phone_number keys.

You're passing in contact to the block, but inside your block, you wrote contact_list. You don't want to access the contact list here. Try changing your two instances of contact_list to contact.
