Prior to purchasing this book I also bought "Macromedia Flash for Windows and Macintosh Visual Quick start Guide" by Katherine Ulrich. I would give that book a 5 star, and purchased this book feeling it would be of the same mold. But I was wrong.
If I were to be honest I would have to say on the positive side that this book is very good from the standpoint of the topics it covers, its structure, and goals.
However, the reason I would only give this book a 3 star rating is because it is full of errors and is often very unclear. I realize that the writers assume the reader already possesses a clear understanding of Flash and will proceed from there. However that is not the problem, but is rather that in may examples the writers are far from clear on where they are going. And there are many errors. For example, when going through one exercise creating radio buttons one is told to create a "movie-clip" and a short time later told to "select the first button instance", but there is no button, only the movie clip the reader is told to create. The book is full of errors like this.
If the purchaser does not mind spending the necessary time to figure out how the writers have arrived where they end up, and going back to correct numerous directional errors the book does have its merits. In the end it is great in concept, but poorly written.
