I think you're better off posting in one of the other targeted .NET forums located here: http://p2p.wrox.com/asp-net-asp-12 , as this one is for the book "ASP.NET E-Commerce Prog Problem - Design - Solution" only.

If you do post in another forum, be sure to provide lots more detail than you have done know. "Server Error in '/gadgetswarehouse' Application" and "please help me" is not enough. You'll need to provide more specific error information, explain your setup (e.g. .NET framework, whether you're using VS.NET or not) etc etc otherwise no one knows how to fix this.
