I'm not sure if this is possible but here is what I would like to do if anyone knows a formula please.
I want to show the duration (in weeks) that a Case is is/was open based on: a) between the Date Opened and TODAY (if Date Closed is blank) OR b) between the Date Opened and Date Closed (if Date Closed is not blank) OR c) leave blank if start date is blank
My columns are: A 'Case', B 'Date Opened', C 'Date Closed', D 'Duration (in weeks)'
See image for example
Thanks, Eva
