I have projects and month wise data which I need to accumulate over time. So, for every project, March 2015 number should show cumulative sum till March 2015. I don't want to use rangesum because I want to apply a condition later which is that if the status of a project is 'Inactive', the whole cumulative number for that month for that project should be 0.
I am attaching sample data ... kindly help how can this be achieved within script.
