A method called balance isn't working for me. Thanks!

Here is what I have:

def balance balance = 0

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

bank_account.rb
class BankAccount
  attr_reader :name

  def initialize(name)
    @name = name
    @transactions = []
    add_transaction("Beginning Balance", 0)
  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 balance
    balance = 0
    @transactions.each do|transaction|
      balance += transaction[:amount]
    end
    return balance
end

Looks like you're missing a closing end for the balance method. Otherwise looks great!

Thanks Geoff! I've tried with and end, it says 'Try again!'. So I'm not sure what is it that I'm missing.
