Can't get 'additional fields' to show

HI
I am trying to set up an event and have the registrants have to fill in a few fields to register and then pay. I have installed the 'additional fields' plugin and added the fields, but can't seem to get them to show up for people to fill in. http://www.petsafecoalition.ca/events/2014/05/disaster-training-weekend-2014/
