Hello,
Ok, may be the reason is really that I am running a bit old Virtuoso,
Virtuoso 5 ver:0.9849.
The script is attached.
Thank you for the help!
Version is too old :-)

Best Regards,

Silvia,
How old is your version of Virtuoso? HAVING syntax is supported not from
the very beginning in SPARQL/BI, it's relatively new thing. Before that
that required a combination of a sub-SELECT with grouping and WHERE in
the outer select, something like
SPARQL SELECT ?s ?total
WHERE { {
SELECT ?s SUM(?books) as ?total
FROM <http://mygraph.person>
WHERE
{
?s <http://mygraph/person/books> ?books .
} }
FILTER (?total > 2) }
