Populate A Popup Window With Clickable Records From An Access DB And Upon Clicking, Populate A Selectbox On The Original Webpage With The Clicked Record

We have an ASP site that hits up an Access database of categories of
products and products. (e.g. Categories = Napkins, Tablecloths;
Products = 20x20 Napkins, 21x21 Napkins, 54x54 Tablecloths, 60x60
Tablecloths)

We currently have select boxes that when you select a category, it
populates the next select box with the proper list of products (i.e. I
select Napkins as a category, I get a listing of the Napkins)

We would like to put a clickable link before each of these select
boxes that would pull up a pop up with links from the records from the
proper table.

(e.g. I click the categories link and a popup with html
anchor tags of Napkins and Tablecloths appear) I click on the Napkins
anchor and it populates the Categories Select box with Categories and
Napkins being selected.
