If in current month, don't use growth %, otherwise use growth %

[losincog]

Hello

I have a forecast for remainder of financial year. How would I create a if argument that if we are in the current "Period", do not add growth percentage but a forecast for a future "Period" should be forecast plus growth for that relevant Period (row 5 in Forecast tab) and country (in col A in Forecast tab). Both the Forecast and Assumptions tabs have dates as well as Periods, if that makes it easier to map a argument

I want the results to occur in the Forecast tab. The growth data is in the Assumptions tab.

(My original workbook, the Forecast tab pulls in data in a not-so-simple manner from accounting system-driven data tab but for this thread, I've just done this simple layout for now)

thanks

Not really sure where you want to show this, but it sounds like you need to use something like...
=if(month(currecnt-month)=month(testing-month), do-this, do that)
