Query: Watse of money

Do not buy this book. It does not teach you anything. It is like a reference manual that is not different than yellow books. If you are not familiar with class etc. buy the book called Practical Lotus Scripot by Patton. It will give you good start. That is all you need to start coding lotusScript and if you need more deatiled info on any subject you can always use the excellent online help of LotusNotes.
