With the helpm of this forum, I have been able to find a formula which does that AND uses values only when they are greater than zero and does not display #DIV/0!. But I cannot fin a fromula that will do the next step- Take an average of those specific cells AND use only the ones where the cell is 0, Example G8=100, G16=85, G24 is blank, G36=75, then this formula would calculate the average 100+85+75/3. All help greatly appreciated For you example, try this formula: =SUM(G8,G16,G24,G36)/SUM(G80,G160,G240,G360) If your data is more regular, say every 8th row, ie G32 rather than G36, you may try something like this: =SUMPRODUCT((G8:G32)*(MOD(ROW(G8:G32),8)=0))/SUMPRODUCT((G8:G320)*(MOD(ROW(G8:G32),8)=0)) This is a longer formula if you only have a few data, but if you have data in every 8th row from cell G8 to say cell G400, then this is shorter. Hope this helps / Lars-Ã…ke . |
