[Plugin: ProjectManager] Nav Links?

I love that project manager can upload via CSV file to create the galleries I’m displaying but I can’t seem to get the nav links for the gallery to display. I’m using the php code randy hoyt created on https://randyhoyt.com/archive/wordpress/snippets/ although, I’ve tweeked the code to display full galleries (using my own css as well). My question is, where and what do I insert (script wise) to display nav links for the images not being displayed? (I’ve restricted the galleries to 40 pictures).
