Automator Action to Add Watermark to Images

Hello all!

Thanks for reading. I recently downloaded the Photoshop Automator Action Pack from Complete Digital Photography and I'm attempting to use the action to add a graphic watermark to an image. I know how to add it manually through photoshop, but I must be doing something wrong because I cannot get it to work with Automator. Can someone PLEASE PLEASE explain to me how to set it up so the watermark will be placed over my images.

This is where I got to tutorial http://www.candeekis.com/pswatermark/pswmtut.html

I selected to have the action use soft light and all, I just can't seem to get it to actually apply it to the images.

PLEASE HELP!

I have even tried other photoshop actions in the pack and nothing is working for me. Either something is wrong with the CS3 pack, or something is wrong with me :\
