A one-event membership is only valid for five consecutive day(s), usually in the future (depends on the start date that is entered during the registration process). If you entered a start date in the future, the membership will not be valid until that date.  On the day you chose for the membership to begin, your status will move to "eligible". After that day(s), the status goes back to "ineligible". Once your membership lapses, you may go back through the quizzard again to choose another membership category.   If you upgrade to a full membership, you will get credit for one one-event membership previously purchased during the same season.
