I'm sorry, I really don't grasp your data layout..........about all I can
suggest is for you to replace the ranges A1:L1 in both parts of the formula I
gave you with the actuall cell addresses that contain your percentages of
interest......like

=SUM(C5,F5,I5, etc etc)/COUNT(C5,F5,I5, etc etc)

I tried it and it still doesn't work.

Here is a piece of the spsheet.

Jan-06 Total Feb-06 Total Mar-06 Total
1/5 1/19 2/2 2/16 3/2 3/16

w w 100% w w 100% w w The w indicates they worked. So the yearly total
needs to show a up to date total in percent.

I have made a spreadsheet to keep attendance based on percentages. I want to
be able to insert a formula in the last column to calculate a running average
total. Example, at the end of March they have 100%, but in April they only
have 50% attendance, so the yearly would be 87.5%.

It can't be that difficult, but I can't figure out how to do it. Plus, I
don't want to change the formula each month.

THANKS
