Hi everyone, I need some help with this excel doc. There are two Question sections, Question 1 and Question 2 and each have two checkboxes. I'm trying to make it so that within each question you can only select one checkbox at a time. So for question 1 I'd like it so that if the first checkbox is checked and you check the second one, the first checkbox would then become unchecked and vice versa. And same for Question 2. I would also like to make the whole doc un-editable to viewers except for the checkboxes. Any help would be much appreciated!
