    Well, your kind of up against a wall with this one. There is no
automaticway of having Fm Pro verify that a name is a duplicate,
especially since there are so many ways that a person can write their
name. Once this is understood, people usually go to some kind of unique
identifier field, that is almost always a number, like a serial number.
But this doesn't seem to be what you are looking for, so perhaps you
might want to try a variation of this workaround:
    Take the two name fields and concatenate the first name on to the
last name, ie: Last Name & " " & First Name. Then you can have the file
perform a lookup on this Full Name field within the database file, if it
returns with a match, then you have a duplicate name, otherwise you
don't. I don't know how effective this will be, but it will probably
work 80-90% of the time if you are really careful with your data entry.
Hope this helps...
