Update Table from Drop-Down Menu

I have an MS Access Database. Inside this database I have a table which holds these fields: Category - Business - Address - Phone - Fax On my webpage I have a drop-down menu that will hold a list of each one of the Category items in it. When I select an item from the Category list I want my table to give me all the businesses in that selected category. (just as a side note, my table is created as a "Repeated - Server Behaviour" item with the items of database.business - database.address - database.phone - database.fax) Problem is, how do I do this? Everywhere I look I keep finding ways to "auto-populate" my drop-down list. But that's not what i want to do. What I want is to populate my table according what the drop-down list item that is chosen. Can you help point me out how to do it? Thanks, Josh
