to_s method

I am replication the to_s method as used in practice, but it says the format is incorrect....

bank_account.rb 
class BankAccount
  attr_reader :name

  def initialize(name)
    @name = name
    @transactions = []
    add_transaction("Beginning Balance", 0)
  end

  def balance
    balance = 0
    @transactions.each do |transaction|
      balance += transaction[:amount]
    end
    balance
  end

  def debit(description, amount)
    add_transaction(description, -amount)
  end

  def credit(description, amount)
    add_transaction(description, amount)
  end

  def add_transaction(description, amount)
    @transactions.push(description: description, amount: amount)
  end

  def to_s
    puts "Name: #{name}, Balance #{balance}"
  end
end

Close! You simply need to return the value instead of using puts.

def to_s
  return "Name: #{name}, Balance: #{balance}"
end

You are doing great! However, the challenge isn't asking you to print (with puts) the result out, but is asking you to return it like what Andrew Hill said. Add this to the BankAccount class instead of you to_s method:

def to_s
  "Name: #{name}, Balance: #{balance}"
end
