Couple issues in your code

  • to_s method should takes NO argument. Make use of the @name instance variable & balance instance method (both have been defined) in the String interpolation.
  • don't use the puts statement, otherwise, the to_s method will has nil as return value.
  def to_s
    "Name: #{@name}, Balance: #{balance}"
  end

hope it helps.

Thanks William for quick reply. Yes it helped!
