I have a value (in this instance it is the number 13 in January 24) that I need to populate in the line item below it in the month of February 25. The entire module is dimensionalized by time (month). The Feb 25 formula is an add months function that references an input from a different module based on the quarter of the current period. The sum function doesn't work at all and when I try the lookup it's doing the opposite of what I want (In this example it is using the Feb 25 date for mapping and populating the Jan 24 column with the values from Feb 25, I need it to do the opposite.)
