Hi there,
Since this is not directly related to my book Beginning ASP.NET 4, would you mind posting this in a more general ASP.NET category here:
http://p2p.wrox.com/asp-net-4-539/. That way, you'll attract more viewers there. Also, be sure to post the relevant parts of your code, as well as a more detailed problem description as currently I don't understand what the problem is.
Cheers,
Imar
