I have a pivot table in which id-number is in key position. I need the right formula for getting out the # of transactions (differ from 0) for each particular id in a single cell. Each row presents a single transaction and there may be multiple transactions for the same id during each year. The sample is pretty small and therefore number of cases is slightly reduced, but I hope you get it. Having been trying it for several hours now with getting error messages for the formula, your help would be highly appreciated.
Small sample file attached describing the problem, please take a look.
