Automation Tools is greyed out

Grant,

What operating system are you using?

In the Photoshop Elements Organizer you can create a PDF Slideshow using the Share button.

Then it gets sent to the Email Client you specified in the Organizer>Preferences>Email

and you can save it to your computer from there.

You can convert open documents to PDF's- but must use outside software to combine them into one pdf document.



In the past I have used Adobe Acrobat Pro to combine multiple pdf documents into one, but it's something I rarely need to do. When I do use it:  I have access to it under my school account and must login to it with my school credentials.  That basically means I can only use it for school related things.

You can get a 7 day trial version-  IF YOU DO- CANCEL IT ON DAY 6 OF THE TRIAL TO PLAY IT SAFE.  I used to do this is desperate "1 time only" sorts of situations.

I only pay $10.84 (with tax) a month for photoshop- and it's a pretty sweet deal- comes with all sorts of stuff---- font's templates that actually work fine- no "trying to figure it out and get it to work in photosahop elements." - plus it can do the pdf thing you were wanting to do.
