Error-Checking Options in Excel 2013

When you choose Error Checking Options from the alert options drop-down menu attached to a cell with an error value or click the Options button in the Error Checking dialog box, Excel 2013 opens the Formulas tab of the Excel Options dialog box. This tab displays the Error Checking and Error Checking Rules options that are currently in effect in Excel.
