Cycle 2.9998 not cycling on load, opts.slideCount displays "undefined"

Would definitely like to learn what's causing these issues and very grateful for any help. This code (below) was working perfectly until last week. See it here: http://www.darinsullivan.com/aiaSustainability.html

                The American Institute of Architects needed to create awareness about its first symposium on sustainability. We created a direct mail brochure to highlight the interconnected nature of the built environment and the broad influence that architectural design decisions have upon quality of life, nature and future generations. The opening side focuses on five key presenters, each one addressing an aspect of the larger problem of failed design thinking and what&#39;s needed now. The closing side presents workshop attendance as taking ownership of the problem by adopting new thinking and methods employed by leaders in sustainable design.<span class="endMark">&#176;</span>
