Project Turnaround Time Calculated Field - "Invalid Custom Expression"

[HannahKr2]

Hi,

I'm trying to set up a calculated field from the Tracking Turnaround Time blog. When I paste the formula in the calculation box, I get an error of "This is an invalid custom expression, please try again" with "480" and "2" identified as the errors.

Is there an updated formula or page I can reference?

ROUND((DIV(WORKMINUTESDIFF(Actual Completion Date, Actual Start Date),480),2)

Thank you!

Try this expression instead

ROUND(DIV(WORKMINUTESDIFF({actualCompletionDate},{actualStartDate}),480),2)
