Many years ago, in the days of Symphony, QuatroPro, and earlier versions of Excel, I used circular references extensively to collect results from different input data sets in extremely large and complex spreadsheets. You could base the selection of inputs and where result data would be stored useing a counter that simply referenced itself and added 1. (Of course you had to set calculations to "manual" and iterations to 1.) Now I have a need to do a similar kind of problem and I can't get Excel to allow and calculate a circular reference. Is this no longer possible? If it is: How? If not: why would they take this capability away?
