Grocery List program problem. Not Sure how to fix it. Please help

Hi,

I followed along with the video, and did my code. Not sure why it is asking the question "What is the item called? And how much?" 3 different times?

I am including my code. I would appreciate it if someone could please look at it.

Thank you

def create_list print "What is the list name? " name = gets.chomp hash = { "name" => name, "items" => Array.new } return hash end

def add_list_item print "What is the item called? " item_name = gets.chomp

print "How much? " quantity = gets.chomp.to_i

hash = { "name" => item_name, "quantity" => quantity } return hash end

def print_separator(character="-") puts character * 80

end

def print_list(list) puts "List: #{list['name']}" print_separator()

list["items"].each do |item| puts "\tItem: " + item['name'] + "\t\t\t" + "Quantity: " + item['quantity'].to_s end

print_separator() end

list = create_list()

puts "Great! Add some items to your list."

list['items'].push(add_list_item()) list['items'].push(add_list_item()) list['items'].push(add_list_item())

puts "Here's your list:\n" print_list(list)

Hi Michael,

I'm not sure what the issue is. In the video, those questions are supposed to print out three times, and it looks like they do in your program. The "add_list_item" method is responsible for getting the name and the quantity of the item. You are calling that method three times at the bottom of the program, but this is correct if you are following the video. If you have any more information about your error, I can try to take another look.
