I am concerned with this bit of code:

#Print Team  
def print_team(team) 

  team_seperator()
  puts "Team: #{team["name"]}\n"

  team["members"].each do |member|
    puts "\tPokemon: " + member['name'] + "\t\t\t" + 
          "\tType: " + member['type']

  end
  team_seperator()
end

Where is the statement that should read "team = __________________"?

I have no idea where you are interpolating the value for ["name"] when you type:

 puts "Team: #{team["name"]}\n" 

I am really confused because you do not have a "team" variable anywhere in the code and it works just the same as the exercise in the video.

For example in the video they have code that looks like this:

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 = create_list() <------ this is what I am looking for in your code.

Hi Maurice, the "team" value that you are seeing is an argument that I am passing into the print_team method, it's kind of like a placeholder as it's telling the method what to expect. I could have called this argument anything like treehouse or mike but i wanted to name it something relevant to what I was doing. I don't have to declare this team argument value as I will be passing my pokemon_team variable inside the method. This is the process:

I created a method that creates my team, this gives me a hash with the keys "name", "quantity" and "members"

def create_team(team_name, quantity)
  hash = {"name" => team_name, "quantity" => quantity, "members" => []}
  return hash
end

I create the team variable using this code:

pokemon_team = create_team(team_name, quantity)

Later on in the code I push the pokemon team members into the "members" array, but let's ignore that for now.

The print_team method takes an argument e.g the pokemon_team hash and prints out the information:

#Print Team  
def print_team(team) 

  team_seperator()
  puts "Team: #{team["name"]}\n" //outputs the team's name (pokemon_team["name"]) 

  team["members"].each do |member|
    puts "\tPokemon: " + member['name'] + "\t\t\t" +  
          "\tType: " + member['type']

  end
  team_seperator()
end

and then I pass it into the print_team method as the "team" argument:

print_team(pokemon_team)

Hope that clears things up a bit :)

Your explanation was great, thank you very much.
