Now, I am using dataform for Moodle 2.7, but I have some radio buttons where the selection is 1 or 0. It shows up fine when making the selection, but when a student selects the radio for 0, it doesn't seem to get saved. As far as I can see, it doesn't even create an entry in the database for it.
Has anyone else seen this problem? I'm trying to use dataform for a skills testing sheet and for some skills you are either awarded 1 point or 0 points. Since there are only 2 options, the radio button worked perfectly, but it seems to think my 0 is a null or nonexistent value when it creates the record.
