Dear respected Curious_George1993,
Good day! Thank you for posting to Microsoft Community. We are happy to help you.
As per your description, you can use a workaround to display negative numbers by modifying your formula as follows: =IF(I44="N/A";"";IF(O44="Completed";"0";IF(I44<>"";IF(TODAY()>I44;DATEDIF(I44;TODAY();"d");-DATEDIF(TODAY();I44;"d"));"")))
Or you can modify your formula to display negative numbers:(In this modified formula, instead of using the DATEDIF function, we subtract the deadline (I44) from today's date (TODAY()).
=IF(I44="N/A";"";IF(O44="Completed";"0";IF(I44<>"";I44-TODAY();"")))
If there is any misunderstanding, I apologize and please feel free to post back to us with more detailed information for better understanding and guiding you further.
Appreciate your patience and understanding and thank you for your time and cooperation.
Sincerely,
Waqas Muhammad
