Hi,
Help needed please. I need to calculate the total data remaining in the year dependant on a month entered. e.g. June-13 entered means 6 months remaining so require the total by "Option" (see attached) for the remaining 6 months.
I have added a basic view of this in the attached. A data file and sumary page. I have tried a SUM INdex but am struggling.
Help much appreciated.
