 Use **IfError** to replace error values with a valid value.  For example, if it is possible that user input may result in a division by zero, replace it with a 0 or other valid value that is appropriate for your app so that downstream calculations can proceed.
 
-Use **IfError** in [behavior formulas](../working-with-formulas-in-depth.md) to perform actions, check the results for errors, and if needed take further actions or display an error message to the user with [**ShowError**](function-showerror.md).
