Have I posted this in the correct group?

I have a stored procedure (named MyProcedure in this example )that runs, a
connection in Excel that is set up according to the help files. When I click
the refresh button I get this message:

[Microsoft] ODBC SQLServerDriver [SQL Server] could not find stored
procedure 'MyProcedure'

When I click OK, it goes ahead and runs finds and runs the stored procedure
, and returns the correct data. I'd like to have my users avoid this message
if possible. Can anyone suggest why I'm getting it and how to avoid it?
Thanks!
