This is really an Access query design question. In your Access datasource
table, you need a field by which you can link each record the the Setup
table and a corresponding field in that table. For example, in each table,
add a field named "link" and in the datasource, enter the numeral 1 in that
field for each record (run a query to do this if you like), then in the
Setup table, enter 1 in that field of the single record (or the record that
contains the path that you want to be used. Then create a query that links
both of those tables on the link field and have it display the data from the
datasource plus the path from the Setup table. When you view this query,
you will see that for each record in the datasource, there is also a field
that contains the path. Use this query as the source of data from your
mailmerge.
