Since I mentioned using calculated fields in Excel, I've had a few questions through about what I imagemeant.  I can see this is an area people are confused about with more people wanting me to record the steps in a video.  However, this is already part of the training which was the point of the post.  In particular if you are struggling with creating calculations based on data in a pivot table, the training course here is all about how to do that with little built in videos and a practice spreadsheet to download and work on.  So can encourage you to take a few minutes to review that as I think it will answer your questions.
