Text for each radio button prompt
Radio button values are stored using a radio group. The value of the radio group is an integer that corresponds to the radio button currently selected. A specific radio button’s value is determined by its position in the tab sequence; the first radio button’s value is 0, the second is 1, and so on. The radio group must come immediately before the radio buttons in the tab sequence.
