Query: This book is [not good]

After reading through the first 20 chapters, in which no programming occurred until Session 16, I finally gave up. When I hit the first source code error in a simple form validation program I chalked it up to a simple typo. In Session 20 I couldn't get their program to work at all, to say nothing of the source code not even appearing on the CD-ROM!Whatever you do, DO NOT WASTE YOUR MONEY ON THIS BOOK!!!... As has been said before, if I could give it zero stars I would.
