Value List or Portal w/no repeat

[SuperMacGuy]

Sorry if this is a common question, but...

I am trying to make a "drill down" UI for users to see only what is relevant. Here's the structure of our data.

This Weeks Books to Print

.....Book Names

..........Sets (group of pages that is manageable in quark, about 8)

...............Page Number

So every week we have different books that print, and throughout the year books will print 6-12 times. The Sets can have any number of pages, and won't come to us in numeric order necessarily. Each set can have different page numbers in it.

I understand portals and have 3 files linked to our main "viewing" file.

In the Viewing file, I have created globals and calculations that will successfully show me only this weeks books (based on the year and print week). In my next portal I want to show a portal or list that displays only ONE iteration of the Set number. Right now I have a portal that actually shows every Set number, and lists them multiple times because every PAGE must be assigned to a set, and thus "Set 1" is listed 4 times because 4 Pages are in Set 1.

So I'd like to have a portal kind of thing or list that lists only "Set 1" one time, and when I click on it (using a button), will show every page and its info in another portal window.

Let me know if anyone needs more specific info on my file structures.

Thanks for the help!!
