Email from Webpage Produces " A 'SendUsing" configuration value is invalid"

I'm new to .NET and just trying a few things out, like emailing. I created a
form in Visual Studio .Net to input some information for generating an email
and I'm getting the following error when it executes both on my server or on
the server of the .NET service provider. I'm obviously missing something
very basic and I'm hoping one of you can point out my error. Thank you for
your assistance.
