Is it possible to base a relationship from portal to portal? Let me try to explain.

Layout from table "Items" Lets say Item name is "Bluetree". Its a tier 4 Item. Tier levels are from 1 -4.

It takes 2 or 3 tier 3 items to build a tier 4 items.

It takes 2 or 3 tier 2 items to build a tier 3 items.

It takes 2 tier 1 item to build a Tier 2 items.

What I would like to do is on the layout.

Portal 1 shows the tier 3 items I need to build a bluetree. (This I can do. The rest I can't)

Portal 2 would list the items you need to build the tier 2 items from portal 1.

Portal 3 would list the items you need to build the tier 1 items from portal 2.

Hope this is clear what I'm trying to do. Thanks

I'm sorry, but to me it's as clear as mud

Got it worked out.
