invalid argument for database

[gagani]

I have added a stored procedure to the tables of the
crystal report.

it was working fine.now when i try to run the same report
it is showing
'Invalid Argument provided.
Failed to open a rowset.
Error in File ...rpt
invalid argument for database

when i removed the stored procedure, it's working fine.
but i want the stored procedure values to be used
in the report.
