Delete All Empty Subfolders

I have an applescript that deletes watched tv shows from itunes along with the corresponding video files in "Users/Username/Music/iTunes/iTunes Music/TV Shows". The only problem is it doesn't delete the folders the files are contained in. For example, the fourth episode of the sixth season of the show Lost would be located "Users/Username/Music/iTunes/iTunes Music/TV Shows/Lost/Season 6/04 The Substitute.m4v", and the Applescript I have will delete the m4v file, but it leaves the empty folders "Season 6" and "Lost". What I'd like Hazel to do is delete the season and show folders if they're empty.

I thought I knew how to do this, but apparently not because it's not deleting any folders.

I'm using TV Shows as the folder.
The first rule is "If all of the following conditions are met" "Kind is Folder" then "Do the following" "Run rules on folder contents".
The second rule is "If all of the following conditions are met", "Kind is Folder" and "Size is 0 bytes" then "Do the following" "Move file to folder: Trash".

What am I doing wrong?

Any particular file/folder can only match one rule. So, all folders are matching the first rule and never get to the second. If you reverse the order of the rules, then it should work as you expect. Try using the preview function to test the rule logic.

I knew it had to be something stupidly simple.

Thanks,
