I'm trying to calcualte average growth percentages from month to month for a 12 month period and my results are being messed up by the #DIV/0! error falling in line with certain months due to no-production. I tried to insert a couple of IF <>0 criteria statements in my formulas and they all failed to work. Can someone please shed some light on this for me? I feel i am close, maybe i'm just making a stupid mistke. Thank you for any help guys.
