Rotating Quotes with jQuery

Rotating Quotes with jQuery

I have created a small rotating quotes display in jQuery. Here is a link to a test page with the quotes:

http://www.upward.org/cheercoordinator/_tempFiles/test.aspx

Here is my issue. My source is the same on staging and production. However, in my staging environment the quotes rotate (fade-in and fade-out) without issue. On my production site the rotating quotes keep repeating the second quote. I do not see what the issue could be so I am asking for additional eyes to look at it.
