Char(1) can't be insert from stored procedure called from C#/ASP.n

Hello I am trying to insert a char(1) field into a table from an ASP.Net/C# application.

Problem debugging Website

I asked yesterday about how to reference a website project in a Unit test project. The answer as you guys provided is that it is not possible. I have no permission to convert this website project into a web application project, so I have to live with it. To add salt to wound, I cannot debug the project. The website is configured to run from localhost through the IIS on my Vista box. This makes debugging pretty tricky, my breakpoints are totally ignored.
