               This “message” appears when the column is not wide enough to display all of its content. You can
               correct it by increasing the width of the column to fit the content correctly.

               This error message appears when you divide something by 0. You can correct it by changing the

               #NAME?
               This error message appears when you have typed a wrong formula and MS Excel cannot recognize it.
