Chapter 6, page 201,Try it out does not work.
In the Try It Out, line 4 requires you to "click Update". When I do so, I get
an error message: System.Data.SqlClient.SqlException. "Must declare the scalar
Can anyone help me by telling me where to go to declare the scalar?
I note that the solution provided in the "End" folder works whereas following the Try It Out from the "Begin" folder does not. So it looks like the authors found a way to solve this problem. I just don't know where to go to do the same thing. Thanks to anyone who helps.
