Automator and OCR?

Hello,
I’m trying to get Automator to work with OCR. I can get the Automator script to work with a single file. How do I get it to take a batch of files from a discrete folder?

I get batches of documents and want a simple way to bring them from my email (where they are pdf) into DevonThink Pro.

Thanks.

The “OCR Items” action works with multiple files. My guess is that the actions you use before this one only select one file.
