$Session, $Tag and $Values are only valid for catalog-level subs, for
global subroutines you should use $Vend::Session $Vend::Tags and
$::Values respectively.

You probably need to open the tables.  You can use something like:

$Tag->perl({table => 'products userdb'});

After a line like that you should be able to access the products and
userdb tables via the Db hash.

For a globalsub you have to get a db record in a different way.

Yes, because the page you access on probably opened the table before you
accessed it with the usertag, but the sub was called sooner before
anything else opened it.
