I am updating an access database that I designed years ago originally in Access 2.0 later transfered to 97 then to 2000. It works perfectly for what I designed it for: database for the dragonfly collection at the Florida State Collection of Arthropods in Gainesville, Florida. I would like to add an new field to my main "table" but get an error that says you "can not modify a linked table." So I did some research a learned how to unlink my table (which is on the same computer as the front-end program. After deleting the link as instructed, i was able to add the new field to the back-end table and save it. I re-linked it to the front end, but my new field does not display. I have "refreshed," deleted and relinked but no gecko. Can anyone help. [both back end and front end or in .mbd format and there are just shy of 90K records]
