I'm having a little trouble with the codebehind example for the Wrox application in Chapter 12. I've copied all of the code into the code behind file, and I've added the namespaces shown in the book, and I've declared all of the controls and variebles. However, I'm getting an error when I run the page:

BC30451: Name 'ConfigurationSettings' is not declared

It seems like the code behind file is not recognizing the Web.Config file. How can I fix this? Any advice?

Thanks,
Devin
