The question is not clear. What do you mean by "modify a record, into a
form"? Why are there identical records, and what do they have to do with
the question?
If you have multiple identical records in a table... your table design is
incorrect. Every table should have a Primary Key, a field or combination of
fields which uniquely identifies one single record. If you do not have such a
field, then Access cannot possibly tell WHICH of the identical records you
want to edit.
