Check for files deleted from a folder

I want to check a folder for any files added or deleted. Added is no problem but I cannot work out a rule for checking if any file has been deleted from a folder. Any help or advice appreciated. Thanks.

What do you want to do if the file is deleted?

Post a Growl message saying there has been a change in the contenst of the folder

You should then monitor the folder above the folder that has files being added and removed. Write a rule to match changes to that folder ("date last modified is after date last matched" should work) and act accordingly.

Thanks that worked.
