The State Code 2 / State Code 3 fields are causing some problems for Australian States, eg we use three letters for NSW, QLD, VIC,ACT, TAS etc but then use two letters for SA, NT, WA. This means some people are getting NS instead of NSW on their invoice etc. I think this problem was overcome in Membership Pro but still occurring in Events Booking - Can you allow two letters OR three letters in these fields (State Code 2/State Code 3) to rectify this problem for us Aussies?
