Drop box loading in PHP

Hi all.

I have the file below that the end user uses to lookup records. Currently, they select a Builder/Community and then based on what the builder/community is the LOT drop down is populated, then based on what the builder/community and LOT are it then populates the BLOCK drop down. But we are running into some instances where we want to first look up by BLOCK and then LOT. How can I change my code below to allow them to first search by BLOCK and then LOT, or LOT and then BLOCK as it currently is, it's up to them to choose how to search. Or should I just create a new page that will allow them to do BLOCK and then LOT searches and keep this page as is?

Thank you in advance!
