When creating a report, it is not allowed to be selected as a group by. When running the detail report, it could show the the Age field, but when switch to Summary mode, it generates the following error
Invalid Parameter: Search Parameter value "howOld" (RequestID: 57bc437101d0739c2d06cdf4fc67f991)
Also, is there a way to create a calculated field based on something like $$TODAY since the 'age' field does not seems to work for reporting summary. I've tried to use DATEDIFF($$TODAY, Entry Date) and got blank. Any insight would be appreciated.
