Hi LNJJNS,
Thanks for your valuable feedback and sharing updates with us and I really appreciate your effort and your precious time doing.
And I appreciate your kind words.
No problem at all! Based on your requirements, we can create a formula for Column N (Deadline Met) that checks if the date in Column P (Date Closed) meets the deadline in Column M (Deadline Date). If no date is entered in Column P, it will leave both Column P and Column N blank.
Here’s the formula you can use in Column N:
=IF(P2="", "", IF(P2<=M2, "Yes", "No"))

In this case, if you think my provided idea is helpful and you can understand my explanation and correct direction on this whole scenario, could you please use the feedback tool to send us feedback? (photo below).
Your feedback really means a lot to the dedicated members of our community.

If there are any issues with Office apps in the future, feel free to post to this community again.
We will be there to help you.
Have a great day and stay safe 😊
Sincerely
Waqas Muhammad
