Newbie Maybe even Stupid Question

I have a database with 2 tables, Catagories and Products,
I have created a relationship between 2 fields,
CatagoryID in the Catagories table and CatagoryID in the
Products table, My question is:
I am trying to build an online catalog and need to
display results to 2 different pages, I am using the
frontpage database wizard to get the connections,
I want to display the results from the Catagories table
as a list in a sidebar frame (side_nav.asp) and want to
hyperlink this list to show results in the (main) frame
on a different page (Output.asp), But, the results I want
to show are from the Sub-Data table (Products), What
would I use as a perimeter for the query to pass the data
from one page to the other? ANY HELP WOULD BE REALLY
GREAT!!!!!! Thanks in advance to anyone answering
this!!!
