Hi,
in frontend registrant management if a registrant is in a country which has no states the dropdown for State is empty and the entry cannot be saved.
If an entry is changed to a country without a state the entry can be saved because an "NA" entry is available. Save is OK. Then try and change another field and save again and it fails because the State field is now empty (contains "Select State").
If I change the country to a country with States such as USA, then back to Hong Kong (no states) it does work.
Thanks,
Russell.
