I add two new fields - Join Now
NEW_ITEM1: - and - NEW_ITEM2:
I wish - 1 field - mandatory
NEW_ITEM1: - or - NEW_ITEM2:
example
if the person - selection - NEW_ITEM1 - it's ok - join now
if the person - selection - NEW_ITEM2 - it's ok - join now
if the person - selection - NEW_ITEM1 - and - NEW_ITEM2 - it's ok - join now
if the person - do not select - NEW_ITEM1 - and - NEW_ITEM2 - it's not ok - join now
