Hi,

Assume that your data is in range D30:E36 (D31:E31 has Monday and Location).
You can try this

=SUMPRODUCT((RIGHT(E31:E36,1)="1")*(D31:D36))/COUNTIF(E31:E36,"*#1")

I have a spreadsheet with headers of the days of the week. Below that is
the
date, then location 1's sales then below that is location 2's sales. It
is a
running year long listing and I want to calculate the Average Sales for
each
day of the week.

For Example:

Monday Location
12/20/2010
$3,523.12 store #1
$4,632.12 store #2
12/27/2010
$3,322.12 store #1
$4,545.12 store #2

I just picked 2 dates that are a week apart. In the example above, I want
to average $3523.12 and $3322.12 and so forth (this would be location1)
and
then separately I want to average $4632.12 and $4545.12 and so forth (this
would be location2). Columns for Tue through Sat are between the columns
in
the example above.

The date being in there throws off using sumif and countif (with location
being the criteria for the count). I hope I'm making sense.
