I have a main form that contains a subform. The subform
is a data*** that allows entry of new rows of data. If
the user creates an entry by mistake, is there a way to
create an "undo" command button that will reset the form
and subform data to the way it was before the user entered
the data?

Right now, I think they have to use ESC button to clear
fields, but some of them don't know to use it. They get
stuck in the form.

Hope this makes sense.

Thanks
