Take a look in your EditSQL (UpdateSQL), InsertSQL and DeleteSQL properties.
Something in there isn't matching up. Also, what are your KeyLinks set to if
at all.

Or, try things anew in a fresh component dropped from the pallette and see
if that clears it up.

IBO seems a littly awnry at times but it just want's to make sure things are
correct in your application... This is one of those cases.

Thanks for coming to the list for help instead of giving up.

Kind regards,
