need some basic help

[Matthew]

I have a basic daily sales sheet that has a number value in column one for
the day of the month from 1 to 31, column 2 has the daily sales that I put
in manually and column 3 has the total sales for the month =SUM(B2+C1). At
the bottom on row 31 I calculate daily average sales with a basic =C3/C1
and I have to change on a daily basis by hand... all extremely basic stuff.
But I'm looking for a way to calculate the daily average sales automatically
as I put in the daily sales each day without having to edit the row 31
formula every day. I tried googling for daily average sales but that kept
giving me moving averages which didn't seem the right direction.

Did you try using the AVG() function at the bottom of ColB?

data. Sorry to bother.. thanks for the help

What's wrong with =AVERAGE()?

You can have =AVERAGE(B1:B31) in a cell like say B32 or B33. The
AVERAGE function ignores blank cells.
