Wait for the 2nd edition,

This review is from: LotusScript (Accelerated Lotus Study Guides) (Paperback)
While this book has some good information, it has too many errors to be useful.
I believe the authors know their stuff, but I guess they were just in too big a hurry to get it out in time for Lotusphere 99 (which is where I bought my copy).
On average, there is one error per 2 pages of this book! Really. It's unbelievable that McGraw Hill would let something like it out. It's not just the explanatory text, but the sample questions are full of errors, too. You have to pay close attention to what is going on in this book because you can get very confused reading it.
Hopefully, the authors go back through it again and reissue it after they've cleaned up the errors. I believe the book could be a big help to anyone studying for the exam once the errors are corrected.
