Help with Actions and Droplets

I am trying to design a droplet, that will allow me to create a contact sheet for pictures in a folder. The problem being, that if I create the action for creating the contact sheet, then I make the droplet, any time I use the droplet, it automatically uses the folders that I specified in the design of the action, the thing is, that I need it to create the contact sheet for whatever folder I drop onto the droplet, not whatever folder was used as a test dummy in the design of the action.

Any help would be appreciated. Thanks
