Automator app to delete a folder (Dropbox Cache folder .dropbox.cache)

Trying to create Automator app to delete Dropbox Cache folders. I could use Apple script but the task seems simple so I decided to go with Automator for the first time. I have 2 issues:

1. The confirmation dialogue doesn't show up
2. If I disable the first step, the app still doesn't run
3. Checking the Activity Monitor shows the app is not responding (force-quit and starting app again is the same result)

It's worth the note the folders I am trying to delete are ".dropbox.cache" hidden folders. They grow in size, every time couple of GB and occupying space in Dropbox. There doesn't seem to be a solution to this issue so I thought creating a small Automator app would make my life easier.

Any advice should be good advice, except if you tell me to read the 100 page Automator manual

Bump...

Both of the folders ".dropbox.cache" folders are hidden and they grow in size to several GB over time. That's the reason I'd like to automatically delete them periodically when not synchronizing or manually using the automator workflow.
