I have tried a simple code to run a basic contact list app but it's not working plz tell me what's going wrong

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

def get_contact

answer = ask("What is your name? ")
contact = {"name" => "","phone number"=>[]}
contact["name"] = answer
answer_1 = ""
while answer_1 != 'n'
number = ask("Do you want to add your phone number(y/n) ")

if number == 'y'
add = ask("Enter a phone number? ")
contact["phone number"].push(add)

end


return contact



end
contact_list = []
answer = ""
while answer != 'n'
contact_list.push(get_contact())
ask(Add Another?y/n)
end 

puts '-'*80
contact_list.each do |contact|

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

if contact["phone number"].size >0
contact["phone number"].each do |phone|
puts "Phone: #{phone}"
puts '_'*80
end
end 
end
puts "-------\n"
end```
