How to weave in Date Information please?

[Danny Boy]

The Formula below works, however I'm having difficulty integrating "date"
parameters into them.

In Column A of the Raw Data spreadsheet I have "Discharge Dates". I want the
two formulas below to work on all data inpuut between July 1, 2009 and up
until Sept 30, 2009. Any data input before or after the date parameters
identified would not register in the calculations. Could someone assist me in
incorporating the appropriate "date" parameters into the formulas below.
Thank you! Dan

=IF(COUNTIF('Raw Data'!$H$4:$H$5000,"Barb B"),AVERAGE(IF('Raw
Data'!$H$4:$H$5000="Barb B",'Raw Data'!$C$4:$C$5000)),"")


=IF(COUNTIF('Raw Data'!$F$4:$F$5000,"OP"),AVERAGE(IF('Raw
Data'!$F$4:$F$5000="OP",'Raw Data'!$C$4:$C$5000)),"")

Rather than use countif and average use two sumproducts where the first
sumproduct is the total and the 2nd sumproduct is the quantity. the two
sumproducts are identical except for the term 'Raw Data'!$C$4:$C$5000. I
made column A the date which you didn't specify.


=sumproduct(--('Raw Data'!$H$4:$H$5000) = "Barb B"),--(date(7,1,2009)<='Raw
Data'!$A$4:$A$5000),--(date(9,30,2009)>='Raw Data'!$A$4:$A$5000,'Raw
Data'!$C$4:$C$5000)/sumproduct(--('Raw Data'!$H$4:$H$5000) = "Barb
B"),--(date(7,1,2009)<='Raw Data'!$A$4:$A$5000),--(date(9,30,2009)>='Raw
Data'!$A$4:$A$5000)

What version of Excel are you using?

 

[Shane Devenshire]

If you are using 2003 or earlier look at your later post. For 2007 you could
use:

=AVERAGEIFS('Raw Data'!$C$4:$C$5000,'Raw Data'!$H$4:$H$5000,="Barb B",'Raw
Data'!$J$4:$J$5000,">="&B1,'Raw Data'!$J$4:$J$5000,"<="&C1)

This is not an array formula but the dates are still entered in b1 and c1.

I am using Excel 2007. Again, the formula below works, however I was having
difficulty when attempting to incorporate the date parameter information.
