Question: "Please help me, if you please on this theory subject. How should make my calculations if I want to take into account the month star for a particular month? 1) easiest way: I cancel the year star and substitute with month star and make element calculation with the base star. 2) first I have to make the element calculation between month and year star and only after this I can make element calculations with base star. Or maybe at the end it’s the same thing? Thanks!!!
