Hi there,
Which book are you talking about? Hard to say, as you posted in the general Feedback cateogry of this forum.
May I suggest you pick the appropriate book's forum from this list:
http://p2p.wrox.com/ and repost your question there, along with more information about where you are in the book and the full code for the page you're working on?
If you post code, can you please paste it in Notepad first to remove color coding and then use the forum editor's Code toolbar button to wrap your code in code tags. Otherwise, this forum messes up the code.
Cheers,
Imar
