The standard cascading select in JIRA is only two levels.  You'll need an addon to provide 3 or more layers (look for the multi-level cascading select in the marketplace)

The other option is to try to relate separate select lists together - this involves vile javascript which usually fails, or I think you can do it with some complex stuff with the "Behaviours" part of the "Script Runner" addon (I think this is possible, but I've not tried it)
