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
