But please, prevent the users errors, adding this code in the beforeDelete event of your Ttable:

if Application.MessageBox('¿Are you sure....?','Atención',mb_OkCancel + mb_IconQuestion)= idcancel then
abort;

I think that dgConfirmDelete (Options) is set to False, to avoid the not customize message.

Best Regards.
Marcos.
