I have created a form where a client will need to click yes or no on multiple rows.

Please help. I have created a client account update form where we need the client to answer YES or NO on multiple rows. I can't figure out how to allow for multiple boxes to be  clicked YES or NO. Instead, it is only allowing me to click one out of the 8 rows of YES's and NO's. How can I make all the boxes be able to clicked and not just one? When you click on another YES or NO, it unhighlights the previously clicked YES or NO. What do I do? Please help. Thank you. Rachel.
