I just upgraded my sites to 2013 and have several forms that have required Choice fields rendered as radio buttons. For some reason even if a value has been selected the validation fails telling the user they must complete the field. However when I convert the radio buttons to Drop Downs they are able to save. I tried changing them back to radio buttons and get the same error. My thought is that since these are forms originally created in prior version that radio buttons are rendered differently in 2013, No idea how to fix this though. Any help is greatly appreciated.
Thanks,
Brad
