Ruby Instance Methods Getting underfined method

I keep getting the following error message:

NoMethodError: undefined method `deposit' for main:Object
from (irb):3
from /usr/local/rvm/rubies/ruby-1.9.3-p392/bin/irb:16:in `<main>'

When I run bank_account = deposit(1000) from using the following code in IRB

class BankAccount
def initialize(first_name, last_name)
    @balance = 0
    @first_name = first_name
    @last_name = last_name
end

def deposit(amount)
    @balane += amount
end

def withdraw(amount)
    @balance -= amount
end 
end

What am I doing incorrectly?

Cheers

Niles V. McGiver -

You're trying to call deposit directly - you need to call it from a BankAccount instance. Try the following code:

bank_account = BankAccount.new("Niles", "McGiver")
bank_account.deposit(1000)

Hope that helps.

Thanks Tommy, I was calling bank_account = deposit(1000), also the code was missing a 'c' in balance for the deposit method.
