Hi all,

I’m sure I’m just missing something easy but here is my problem. I have an employee start date field and a field with numbers of days. I have tasks that need to be done 5 days before the employee starts, 1 day before the employee starts, and so on and so forth. So I want to calculate a field using the Start Day and Number of Days to calculate the Due Date of the task based upon number of days.

So if my start date is 6/20/19 and my Number of days field is -5, I want a formula to return 6/15/19. I have tried the formula below but I get NaN returned. Thanks for any guidance and help!

DATETIME_FORMAT({Start Date},‘MM/DD/YY’)+{Number of days}
