Need help with appending a hash into an array

It might just be because it late, but I am stuck with this part of the question. Ive tried a few of the things that you see in the previous video but none work. Im not sure if I have to add to the code or alter the method i already have.

bank_account.rb 
class BankAccount
  attr_reader :name

  def initialize(name)
    @name = name
    @transactions = []
  end
  def add_transaction(description, amount)
    @transaction.push(:description, description, :amount, amount)
  end

end

To push a hash, first you need a hash literal, i.e. two curly-braces (also note that the instance variable is transactions, plural).

@transactions.push( {} ) # pushes an empty hash

Then inside the hash you need two key-value pairs:

@transactions.push( {description: description, amount: amount} )

Or with hashrocket syntax

@transactions.push({:description => description, :amount => amount})
