Wrong number of arguments (0 for 2)

I am currently working on a small school project (Ruby) but I am getting this error (Wrong number of arguments (0 for 2)) that makes me wanna flip a table. :(

This is the code that I am trying to get to work:

puts "How much does the product cost?"
price = gets.to_f.round

puts "How much money will you give for it?"
money = gets.to_f

change = calculate_change(price, money)

I use that to get the user input, round the first to a fixnum and then the second one to a float. This is how my calculate_change method looks like:

def calculate_change(price, money)
    return money - price
end

Per @hirolau's comment, you need to make sure you declare calculate_change() before the call to it.

def calculate_change(price, money)
    money - price                    # return is optional in Ruby!
end

puts "How much does the product cost?"
price = gets.to_f.round

puts "How much money will you give for it?"
money = gets.to_f

change = calculate_change(price, money)
