Not passing checks for printing value of hash keys

The challenge asks -

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.

My code is attached. I also tried another way, both works in Repl.it - https://repl.it/EXBV/0

Not sure what's wrong here.

contact_list.rb 
contact_list = [
  {"name" => "Jason", "phone_number" => "123"},
  {"name" => "Nick", "phone_number" => "456"}
]
contact_list.each { |contact| contact.each {|k,v| print v}}

OK, so the challenge is asking you to print only name and phone number values. Your code is more universal and would print all the values that might find their way into the hash (for example, if you add "age" => 21, this would be printed as well). You need to explicitly print the selected key values, nothing more:

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