Hi, per the screenshot below, I wanted to calculate a compounded growth rate for 3 years based on quarters. Let's say user selects Qtr 20131 all the way to 20143. the formula that i use is
however, it is only calculating it by quarter for example for 20143, it is taking ((1,000 / 0)^(1/3))-1 which gives me error. and so on... What i wanted is to take current sales for the quarter selected by user and compare that to sales at 12 quarters back (in QuarterID) to get the answer.
