My radio buttons won't update with my form. They will update if you change it. But it won't allow it to update if you try to submit the same value that already exists in the database.
The mysql setup is tinyint unsigned.
Any idea as to why it would allow an update if you change the value but not when submitting the same value?
Thanks
