I was trying to import data using web services against a radio button. The value 0 is assigned to the "No" and the value 1 is assigned to the "Yes" answer in my CRF.
Every time I imported the value 1 it was fine, but when I imported 0 the value wasn't recorded in the database (the radio button remained unchecked). According to the web service messages everything went fine but I have missing radio button values.
Has anybody else experienced this issue before?
