Delete those two line and change the syntx if require this will work fine. I thing those you are having trouble is for non empty data cell.

Unfortunately stocks go down as well as up so I can't be sure that I won't have a negative value among the results. Since you can't compute the geometric mean if negative numbers are involved, I needed a way to both convert percentages to 1.x or 0.x values AND subsequently compute the mean. And I refuse to keep my stock performances as 0.9 instead of -10%. Hence I had to find a way to do the conversion in the background, "remember" the values and compute the mean of those. I see what you're trying to do with the formula, but then I'm also refusing to believe that you can express my 30 lines of code in one single line! :-D Luckily, Excel proves me right and gives me a big fat #VALUE! when I try to use your formula on my old -10% and 30% example. :-) Apologies if I wasn’t terribly clear… my problem basically was that I want to maintain an Excel spreadsheet with stock or fund performances on a weekly and/or monthly basis.
