In a current event I have several Radio fields that are required fields. When users register for events and these fields are not selected the software allows the user to continue. I also note that the default selection does not highlight as I would expect. I changed one of the fields to a drop-down style field and it worked as expected requiring one of the options must be selected to continue with the registration. The event is the 2021 Hydraulic Training. For now I am leaving the field as a drop-down field.
