I have a formula in a column for the number of a days a ticket has been opened.
=IF(Status@row <> "Completed", TODAY() - [Created Date]@row, "")
I want to add a metric in the sheet summary to tell me the average days of open tickets. I am using =ROUND(AVG([Days Opened]:[Days Opened], 1)), but this is accounting for closed tickets. How can I add a formula to only average the lines will values aka open tickets?
