//The purpose of this script is to scroll news items from bottom to top with the message changing each time.  It is capable of rotating any number of messages as long as the number is stated in this script as totalNumMessages.  Each individual message is comprised of a title, it's message and a link (in the format of title1, title2 ...title200).  Even if you don't need all components of a message it is still important to define all variables just set them equall to " ".
