Average a part of a on going column
Hi!
One way: Assuming the numbers are in column A, A1:An. There are no empty/blank cells within the range and there will always be at least 30 numbers to avg: =AVERAGE(OFFSET(A1,COUNT(A:A)-1,,-30)) If there are empty/blank cells then it's a little more complicated. Also, if there were less than 30 numbers how would you want to handle that? Biff "Capt Bill" wrote in message ... I need to average only the last 30 entrys in a column of data automatically.
