Issue: A member wants to make entry in the fair in their "Second 4-H county" instead of their primary county. The members imported into FairEntry were keyed on their "4-H county" field, not the secondary. So the member does not see the second county fair as an option, and they're not on the fair's member list.
Solution for this year: TEMPORARILY go into the member's record in 4HOnline, and change the 4-H county field to the second county. Save. The second county fair manager should then do a re-import of members so that one is included. After that import, the member's 4HOnline record needs to be returned to its original state, with the first county back in the 4-H county field.
