Hello,

I am new to asp .net programming and have been using the book ASP.net
3.5 for dummies.

I had the shopping cart on chapter 18 working it seems to use a class
to store cart items using a profile but now I am getting an error. I
show the error and the entry in web.config.
Any ideas what has changed on my system to stop this working. I did
install SQL Server 2008 on my PC but the website code is straight from
the book downloaded and not changed.
