countif, sumproduct

[mg]

table:
1.5.2006 blue
2.5.2006 green
30.4.2005 green
21.5.2006 yellow
21.6.2006 blue

how can I count all the green guys with the datum after 1.5.2005?
countif will not probably work...

I will assume the first column are dates
With dates in column A and colours in B
=SUMPRODUCT(--(A1:A5>DATE(2006,5,1)),--(B1:B5="green"))
best wishes

Hi,

Just out of interest more than anything but what is the signifcance of
the "--" that appears before each argument as opposed to "*", that
Excel Help puts between the two arguments?

Cheers,

what if i need to use a range in the date f.e. from 1.4.2005 to 2.5.2005?

Hi

The -- coerces a TRUE result into a 1, and a FALSE result into a 0. This can
then be used to calculate with.
If you type =FALSE in a cell, it will give the result of FALSE. If you type
=--FALSE into a cell, you will get 0 as the result. Other ways of doing the
same job are to use a * to multiply or even a +0. It's just a way of making
Excel treat logical results as numbers.

Hope this helps.

Hi

Try something like this:
=SUMPRODUCT(--(A1:A5>=DATE(2006,4,1))*(A1:A5<=DATE(2006,5,2)),--(B1:B5="green"))

or

=SUMPRODUCT(--(A1:A5>=--"2006-04-01"),-(A1:A5<=--"2006-05-02"),--(B1:B5="gre
en"))
