Here is the relationship graph.
Presumably, your layout is based on SalesOrder. Given the relationships shown, a portal to Futons or SoftGoods won't show any data until at least one record in SO_LI with an Item ID that matches to a record in one of those tables is created in your portal.
You'd need to set up a relationship that links directly from SaleOrder to the tables referenced in your selection portals for this to work.
I suggest simplifying your design by using a single unified table of all your produducts, but with a category field you can filter on for your different portals.
