I am trying to work out how to creat a 4 step filter.

In box 1, I select a location, then in box 2, I want to be able to select
floors that only relate to the location selected, then in box 3 I want to
select departments that relate to the floor and location, etc..... until I
have 4 stages of information

I have found how to do the 2 stage but cannot see how to continually filter
this between all the data I have.
Any help would be great
