create a table which includes a long field (100s of characters) and an id field. then whenever someone posts a review, add a record to this table with the id of whatever they're reviewing and the review itself. you could also have a field for poster (username or handle), time of post (=now()) and title of review, if you want something slightly less basic.
Then it'd just be a matter of doing a query for whatever fields you want where id = the id of the product being viewed, using that to open a rs, and doing 'do until vrec.eof' and 'vrec.movenext' to fill out subsequent rows of reviews...
