Hi,
Having a hard time trying to help myself with this one, so I am posting a
question...

I want to set a field in my table to have no duplicates allowed except for
the Default Value I assign to it... I want to accept multiple entries of the
default value, but only single entries for all else...

Possible?
Thanks in Advance...

Coolbreeze,
Sounds like that will have to be handlked at the form... more so
than the table.
A field is either Indexed NoDupes or Dupes Allowed. No way to mix...
Make the field Allow Dupes.

I'll assume that the value that can be duped is ALWAYS the same.

At the form level, you'll need just let the Default Value do it's thing,
and not
worry about it. But when you manually override that default value, you'll
need
to do a DLookup against all your other values... to manually make sure that
it's not a dupe.
Use the Before Update event to check for dupes... it allows a Cancel =
True,
in the case of a dupe.
