Clay,
My data connection is working properly because I can use the same stored proc with different parameters to fill textboxes.
Everything I am doing is behind in code...I'm using ADO.NET (C#) a sqlDataReader to read in the data.
I would use the InfoPath UI to set the values of the dropdown, but I need it to be dynamic as possible, and I don't want to hard-code the parameters in the 'edit sql' of the data connection. If there is a way to pass a value from the form to the 'edit sql' in the data connection wizard that would solve my problem.
Thank you for the response Clay...you're awesome!!
