I have simple circular references in cells in a spreadsheet, yet I am unable to press the circular references button in the error checking tab in the formula auditing section of the formulas ribbon. I even tried to put a super easy circular reference in cell A1 by setting it equal to itself plus 1 (=A1+1). I have tried to select the cells I know have circular references and selecting the entire worksheet along with selecting empty cells before trying the use the circular references button, but to no avail. Thanks in advance!
