Online Search Relationship help needed

[vr5150]

I have a online inventory website that has 68 categories and of those it has 197 sub-categories.

I have 3 databases. 1 Inventory, 1 Categories, and 1 Sub-Categories.

They are setup relational and work properly. (at least I think)

Now here is the problem:

When I do a search for a item via a value list on the web it find 207 matches which is correct but I only have 3 sub-categories and it displays all 197 of them. How can I make only show the sub-categories that are associated with this category?
