Moving "Folders Inside Of Folders" Inside Monitored Folder

Hello I'm new to Hazel but have read posts about moving folders and running actions on folders etc. I can only seem to get actions to run on folders directly inside of the monitored folder - not the folders within the folders in it.

I've seen a post about adding script from a few years ago, I wasn't sure if that applied or there is an updated solution.

Specifically what I am trying to do is, this:

I run a recording studio, i'm monitoring a folder called "Client Database" with sub folders for each individual client, and inside each client folder are project folders.

I'd like Hazel to run inside the client folders and move all project folders that have not been modified/active in the past 90 days to a different folder "named" "To Be Deleted"

I really tried reading and understanding before posting this, thanks in advance for your time.

Check out the sticky article on subfolders at the top of this forum. It shows how to set up a rule to tell Hazel to go into subfolders. Add that in addition to your rules which do the actually filing. Post back here if you run into specific problems with it.
