Firstly when I downloaded the chapter and opened the website the SqlDataSource connection string did not automatically appear and I had to browse for it. Then when I built the index page for the catalogue and tried to run it the following error appeared (see below)

can anyone explain what is going wrong & how to fix it?

thanks
