Thanks Lal Babu, you are always there for rescue. I was just taking up this exercise and I had forgotten to Enable the analyses, which I realized after your reply. Yes all of the analyses have started running incl the 'Gas Gravity Avg' as directed in the exercise. However there is one particular 'Production Rate' which still shows "PtCreated". the secund one shows inconsistent UOM's. These were imported from the xml's in the example kit.
