Hello!
Variant B - using rDBAction -> Using rDBAction toolbars and menus in form the first point says:
Add reference to rDBAction to uses part of form.
I think it should be
Add reference to
dm_rDBAction to uses part of form.
Also I think it would be good practice to suggest addition to the uses clause of the implementation section - but maybe this suggestion would made it too complex for a beginner.
Best regards,
Peter
