Just Missing Folder Contents

[Pamelane]

I know this will be something obvious but I've read everything suggested and still I've been scratching my head for days with no breakthrough.Seeking Hazel's help to label all the folders that still contain MP3 (as opposed to any other format) orange. I've tried:

If ALL are Met
Kind is Folder AND
Contents Contain mp3

Run Rules on Folder Contents (downloaded here)
Set Color Label Orange.

Preview reveals "Contents Contain mp3" is not matched and I can't see what else to try.

Since you want the rule to apply to a folder, and not its contents, you need to use a nested condition (and not the "Run Rules on Folder Contents" action). Check the manual on nested conditions as there are more details there.

Thanks so much!
