Display Slide [title] in Pagination

First off thank so much for the plugin! I has allowed me to use it in almost just the way I am looking.

I have implemented a version of the slider here PASSWORD: view

I have built out the pagination so as you see it is now on the side almost as thumbnails. I was hoping to be able to implement each slide [title] into each <span> with an echo. However, after much ado I haven’t been abel to find where in the file structure. I see it could possibly be in the slideshow.php which creates the pagination, however when I put the echo in said span it just shows as undefined.

Any help would be much appreciated!
