Please help a newbie with self-join relationship / value lists
I've been using Bento but looking for something that will work better. I think what I want to do is easily accomplished but i'm coming up short. I have a database where I've setup 1 table at this point. When I select a value for "Lamp Type", I want the "Lamp Size" values to only show either the "T8 lamp sizes" or "T12 lamp sizes" value options based on what was selected.
