[support] Calendar view showing updated date, not event start date

Hello, I've got a drupal 5.1 site, and I've created a view to display the calendar. Which it does: http://beta.menashalibrary.org/childrens/events But, it's listing those events by their creation/updated date/time rather than the start and end date/time for the event itself. Any ideas how I can fix this? - jody
