thank you roger!

i'm not strange of this solution, this is the 'hard-coded' solution.
also,i know how to link one query to another through
mastersource/keylinks or paramlinks. the issue is that i can link a
query to only one query through mastersource, and i need to link one
query to one,two or more different queries. i'm not sure if this can
be accomplished in some 'automatic' kind.

thanks again roger, hope somebody can give me more advices to
accomplish this, until then i'm starting to code in the 'hard way'

best regards,
