Is there something wrong with my bank account methods, method calls or end statements?

I have been working on this task and watching the related video multiple times and I seem to be stuck.

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

bank_account = BankAccount.new("William")
bank_account.debit("Deposit", 500)
bank_account.credit("Withdrawl", 100)

end

Instead of def balance(transaction), try def balance().
