.push command

Ran the code as follows.

ruby 1-symbols.rb

1-symbols.rb:9:in deposit': undefined methodpush' for nil:NilClass (NoMethodError)

not sure why it's kicking back that error, code is same as Jasons. 

class BankAccount
    def initialize(name)
        @name = name 
        @transaction = []
    end

    def deposit(amount, options={})
        options[:memo] ||= 'Regular deposit.'
        @transactions.push({:amount => amount, :memo => options[:memo]})
    end
end

bank_account = BankAccount.new("jerry")
bank_account.deposit(100)
bank_account.deposit(100, {:memo => "This was a gift."})

puts bank_account.inspect

Make sure your @transaction/@transactions instance variable is either singular or plural in ALL lines where it appears. Otherwise these are two different variables.

Thank you for the swift reply. Knew it had to be something simple which it was.
