Add Portfolio Category Sort

Hello,
I have been trying for the theme developer to help but have not gotten a response for my request. I think this is a relatively simple request but you be the judge. This theme comes with a Portfolio function which is for image galleries. I’m using it to display bios and project information. I need it to sort between different portfolio categories and thought the ‘category_name’ was the right argument to pass but when I do, a message appears showing it skipped the top part of the page.

I’ve also tried going through the Codex but few of my ideas render, so I’ve decided to give the forums a try.

Would there be a way to add a structure at the top that says, ‘while category_name is the same as ‘leadership’ do these posts’? How could I construct that?

Thanks in advance,
