Drop Down Menu Control

Drop Down Menu Control

In Zoho DB & Reports is it possible to structure Lookups dependent on the value of another field. For example, if from the the Drop-Down Menu for Field "Chapter" one choose ' North ', then the Drop-Down Menu for the next Field "District" would present only those Districts identified as belonging to North Chapter.

I have seen where Creator can do something like this using scripts, but if I have to use Creator, then how can I "connect" Creator applications to my DB?
