bank_account.rb:32:in `initialize': wrong number of arguments (1 for 0) (ArgumentError) from bank_account.rb:32

I get an error on line 32, been sifting through the code, can't seem to find it.

class BankAccount
    attr_reader :transactions
    include Enumerable

    def <=> (other_account)
        self.balance <=> other_account.balance
    end

    def intialize(name)
        @name = name
        @balance = 0
        @transactions = []
    end

    def deposit(amount)
        @transactions.push(amount)
    end

    def withdraw(amount)
        @transactions.push(-amount)
    end

    def balance
        @transactions.inject(0) {|sum, iterator| sum += iterator}
    end

    def each
        @transactions.each{|transaction| yield transaction}
    end
end

account1 = BankAccount.new("David Czerepak")
account1.deposit(100)
account1.withdraw(50)
account1.deposit(500)
account1.withdraw(21)

account1.each do |transaction|
    puts transaction
end

Hi David,

bank_account.rb:32:in `initialize': wrong number of arguments (1 for 0)

This means, you haven't define method properly called initialize, it takes zero arguments and you misspelling "intialize" in line 7, see below

    def intialize(name)
        @name = name
        @balance = 0
        @transactions = []
    end
