I have 2 worksheets. One named Daily, one named weekly. The A columns of
both sheets have dates. Daily has every business day (including
holidays) and weekly has every Friday(including holidays). The B
columns contain volume that coorelates with the dates. What I would
like to do is take the Average values between 2 Fridays and put them
into the weekly worksheet. I had success with the first week because I
was only searching on one criteria, but when I tried to search between
dates, no luck. This is the formula that worked for the first cell:
{=AVERAGE(IF(Daily!$A$4:$A$604<=Weekly!A4,Daily!$B $4:$B$604))}


Here is the formula I attempted the DID NOT work in calculating the
daily average of one weeks voume.
{=AVERAGE(IF(AND(Daily!$A$4:$A$604<=Weekly!A5,Dail y!$A$4:$A$604Weekly!A4),Daily!$B$4:$B$604))}

Any ideas? FYI, I want to skip the blank cells(holidays) in my
calculations.

Thanks,

Gimi

Try...

=AVERAGE(IF(Daily!$A$4:$A$604Weekly!A4,IF(Daily!$ A$4:$A$604
<=Weekly!A5,Daily!$B$4:$B$604)))

....confirmed with CONTROL+SHIFT+ENTER.

Hope this helps!

That worked, excellent. Thanks Domenic. One last thing, how do I get it
to ignore blank cells (holidays)

It worked. Thanks again. One more thing. Is there a way to set it so
that if there are noe values to calculate, you don't get the #DIV/0!
error?

Sure, try the following...

Insert Name Define

Name: BigNum

Refers to: =9.99999999999999E+307

Click Ok

Then try...

=LOOKUP(BigNum,CHOOSE({1,2},0,AVERAGE(IF(Daily!$A$ 4:$A$604Weekly!A4,IF(D
aily!$A$4:$A$604<=Weekly!A5,IF(Daily!$B$4:$B$604< "",Daily!$B$4:$B$604)))
)))

....confirmed with CONTROL+SHIFT+ENTER. The formula will return 0
instead of #DIV/0!. If you'd like the cell to be blank, you can custom
format the cell...

Format Cell Number Custom Type: [=0]""

Hope this helps!
