Fair enough, but "how do you install specific names in mail merge Word 2003"
doesn't mean anything to me, either, so my first thought was "what word
processor or mailmerge process uses the term "install names" and/or what
does that mean to you?

But if you have got to that part of Word's dialogs, this is what is going
on:
a. the dialog allows you to filter the data source for a merge by
specifying conditions for one or more fields (or "columns") in the merge
data source
b. for example, if the data source contains a column called "lastname", you
might want to select records in the data source whose lastname column
contained "Smith". If so, you should be able to select "lastname" in the
dropdown under the "Field" column in the "Query options" dialog. Then you
could select "Equal to" as the 'comparison', and type Smith in the "Compare
to" box.
c. if you want to specify more conditions, you can specify more
"Field,Coparison,Compare To" combinations.
- if you specify "And" in the very first column, the data source record
will only be selected if it mmets the condition in the row before the "And"
and also meets the condition in the row containing the "And"
- if you specify "Or" in the very first column, the data source record will
be selected if it meets the condition in the row before the "Or", or meets
the condition in the row containing the "Or", or meets both conditions.

if you specify a combinatin of "Ands" and "Ors", things may be a bit more
complicated.

If that sounds incomprehensible, please try to spell out what exactly you do
not understand, and we can try to work out what it is that you need.
