Calcualted column formual “=TEXT(NOW(),”mm/dd/yyyy“)-[Last Update]” will show 44,055 if the [Last Update] column is empty

Question

I am working on an online SharePoint site, and I created a calculated column with the following formula:-

=TEXT(NOW(),"mm/dd/yyyy")-[Last Update]

now the formula is working well if the [Last Update] contain value, while if the [Last Update] is empty then the formula will return 44,055 so how I can fix this? to force the formula to return null if the [Last Update] is null?

Answer 1

Try using this:

=IF(ISBLANK([Last Update]),"",TEXT(NOW(),"mm/dd/yyyy")-[Last Update])
