I've been trying to find an answer to my question with no luck.
Here is what I'm trying to accomplish.
I have a directory and on each page I want to display on the header which is the first last name on that specific page and also which is the last last name on the page.
Remember it has to be in the header, not the footer, and it has to have the first "last name" displayed on the page and the last "last name" displayed on the same page.
Thank you for your help!
