I am using a radio button grid. When the survey taker clicks on one of the buttons in the grid, it is possible to change the button on which they clicked, but not un-click it entirely. I’d like for them to be able to un-click completely and leave the row blank. There is a fill-in option and it they click it on accident, they cannot un-cilck it. Is there a way to change the settings of a radio button grid so that if a survey taker decides not to answer a questions in that row they can un-click the button?
