Hi Alison, Can you please provide details of the actual sample query parts that work and the the query(s) that fail when combined ?
Also, what SPARQL endpoint are you querying is this a public Virtuoso hosted endpoint or your own local instance ? Please provide details of the service and if it is your own the Virtuoso version in use ...
