Using Combo Boxes

[geoffwbailey]

I want to use three combo boxes to select data from a table. The area, process, and product are the choices for the combos. There are multiple areas, with the same multiple processes. Each process has multiple products. I have all this data in a table and I want to be able to specify what i see. I also want it to show all data for the criteria if I select nothing. What is the best way to go about this and how should I start?

That sounds like a Cascading List: http://www.fontstuff.com/access/acctut10.htm
