What's the problem in my code? shopping_list.rb:38: syntax error, unexpected tIDENTIFIER

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