"Member PARAMETERS does not evaluate to an object".

Perhaps I need to build input and output parameters and append them to the parameters collection (?) I'll play with this a bit more.

lnResult = oCM.Parameters(0).Value
Actually it's the way it works with SQL Server SP's. I'm not sure about VFP but you can try.
