Then I think you should split up the result of PrevNextForm somehow and
reassemble it in the desired way.

If you use plain DBI, you have to go that way. Of course you can hide this
in a custom module.

If you use DBIx::Recordset, you can create a DBIx::Database object in your
startup.pl file and refer to it inside your scripts, like:

[-
*set = DBIx::Recordset -> Search ({ '!DataSource' => $main::db, '!Table' =>
.... }) ;
-]

This only works if you export the function foo from mymodule. Then it will
work, of course. The perlmod manpage should give you some information on how
to do it.
