Convert Audio File to WAV-Script Problem

I’m trying to create an Automator script that allows me to drop MP3 files on it and have them converted to WAVs and saved in the parent folder.

My Application workflow is the following:

  1. Get Parent Folder Action
  2. Set Value of Variable: Storage
  3. Import Audio Files (WAV Encoder)
  4. Move Finder Items to: Storage variable

It works, BUT it converts every file in the parent folder not just the one I select.

Any thoughts would be greatly appreciated!
