DATEDIFF not working as expected

Looking to do a fairly simple formulae where it returns the number of days remaining from column "Last Release" and todays date, but I'm getting the error that the start date cannot be greater than the end date, and as such when I go to the first line of the error it's the first date that is > todays date.

 

Any advice on what I can do differently here? I simply wanted to return the number of days and if the "Last Release" date is > todays date then return a 0 or "Out of Contract" message.

@nh27 I am shocked, shocked I tell you, that you are having an issue with TI functions. Just subtract them and you will be fine. No need to use DATEDIFF if you are using DAY.  So, just:

([date1] - [date2]) * 1.

 

Word of warning, I don't like TI functions. This is one of the reasons why.

Also, not shocked...

 

Also, DATEDIFF technically isn't a TI function.

Thank you Greg, I woke up this morning and read this and I can't believe I didn't think of just doing a simple subtract. Have just done this and it works perfectly, thank you very much.

 

I will be having a read of the link you shared as I think I am slowly starting to feel your frustration with the TI functions also 🙂
