I have a spread sheet that has a rolling 12 month formula based on calendar months and that cell is divided by other numbers in another formula cell on several lines by client. I need to add a note to one of the cells for one of the months. Someone stated that this may affect my formulas in all areas. Can someone please confirm if the formulas will be affected in any way. I have another basic spread sheet with 1 set of formulas and have never had the problem with adding notes. I appreciated your feedback!
