Ruby Bank Account Balance Method

I'm not sure what's wrong with my balance method. The interpreter isn't really giving me feedback, it's just asking me to try again.

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
      end
      return balance
  end
end

Hello Patrick,

In your balance method you need to access the amount value from the transaction hash using :amount. Your code is currently trying to add an array to a Fixnum.

Accessing the amount value would look like this.

balance += transaction[:amount]

I hope this helps.
