I see a lot of other problems: you have 3 independet tables. Your 2 queries
(selects) returns 2 independet results, you can't use that for insert into the
3rd table. And i think, you are looking for an update, not insert. So you have
to define how your tables are linked together (join).
Can you explain how these tables are linked together?
