Hi,
I can understand that you are frustrated but perhaps your a bit too harsh here.
I don't know the book, but the error you give indicates that jQuery dollarsign isn't defined yet.
Are you sure you linked the jQuery javascript library correctly ?
I've looked myself ones to the example code for this book (for which you can find links on top of this very thread). And in chapter 15 it shows that genre.aspx uses a masterpage Management.master and in this Management.master jquery-1.4.1.min.
js is linked.
I hope you can get over your frustration and look into the code examples.
I trust you will find it instructive and perhaps will reconsider your opinion on the book.
