I submitted this question about 3 hours ago but it never showed up....sorry if this appears as a duplicate later.
Form created using Adobe Designer has radio buttons because person is allowed to choose only one option, but I cannot set the tab order within the section of buttons. You can tab to the first radio button but when you hit the tab key again, it takes you to the next section of the form. You must use the mouse to click on the desired radio button you want if you want something other than the first choice.
