I’ve now got to this formula :
IF(LAST_MODIFIED_TIME(Status) != “Complete”, WORKDAY_DIFF( TODAY(), CREATED_TIME({Date created})) )
It doesn’t seem to have changed anything and still giving me negative values in the cells.
OK, so there’s a couple of things there that don’t look right:
- You can set up a “created time” field for each record. I would do it like this to just get the date value:

- You can then set up a WORKDAY_DIFF formula. Configure this so that the earliest date (created date) is first. Something like:
WORKDAY_DIFF({Created Date}, TODAY())
You should find this will give you positive numbers for the number of days.
- You don’t need to worry about the existence of the created date field as this will always be populated (if set up as described here). So now your formula can be:
IF({Status} != 'Complete', WORKDAY_DIFF({Created Date}, TODAY()))
You can’t do this, I’m afraid:
LAST_MODIFIED_TIME(Status) != “Complete”,
