I want to be able to select a various range from one column and
average the numbers. Then, paste the average to a different cell.

For example:
Select cells F4 thru F12, then average
Paste average value in cell J4
Select cells F13 thru F21, then average
Paste average value in cel J5

Always the same # of cells to select, and always putting the average
in the next cell in the "J" column. I need to do this for about 50
iterations. Can anyone offer some assistance?

Thanks.
