I am building a spreadsheet to track the growth of data space on a hard drive.
I have my formatting and beginning formula down. However I am having difficulty getting the formula to "move" across columns. The reason for moving is to separate the months, yet have the growth data move across to get a historical estimate of data.
Estimated Disk Growth.xlsx
Any assistance on how to get the formula to "move" with changing columns. I can't seem to get it to work.
Thanks.
