Hi James
Glad you are sorted.
No you don't have to use the double unary. I always used to use the "*" ( or
"+" if you want OR in stead of AND) but I was guided by a very good treatise
on Sumproduct by Bob Phillips.
Take a look at
http://xldynamic.com/source/xld.SUMPRODUCT.html
It is a fairly long article, but well worth the read.

Hi Roger,
Thanks for taking the time to explain this.
I mucked around with the formula a bit more and got it to work without the
doubly unary minus signs (hyphens to me!).
Although a different example, my formula is
=SUMPRODUCT(($B$2:$B$7="Orange")*($C$2:$C$7="Blue" )*(D2:D7="yes"),$A$2:$A$7)
and so it looks for "orange" in column B, "blue" in column C and "yes" in
column D, then sums the relevant numbers in column A
Is this incorrect; do yuo have to use the double unary minus signs?
Thanks again,

Hi James.
Glad it worked for you. Thanks for the feedback.
The -- (double unary minus) is used to coerce the True/False results into
1's and 0's.
So in the first part of the formula the False, True, False, True, True
result from testing whether the value in cells B2:B5 = "Orange"
get changed to 0,1,0,1,1. The second part becomes 0,1,0,1,0.
So with 3,4,4,5,6 as your values in column A we get
0*0*3 =0
1*1*4 =4
0*0*4 =0
1*1*5 =5
1*0*6 =0
which get summed to give your result of 9.

Roger,
It worked a treat - many thanks.
Hey, what's with the -- in the formula?

Try it and see. If the data is as you say, then the formula given will
return the value 9.

Hi,
I picked up the mistake with the "orange" vs "oranges" ...... and I looked
up the sumproduct function at work today, and it appears to be a
multiplication function based on arrays. I want to SUM a column based on a
SUMIF of two columns - not sure if SUMPRODUCT would do this?
Thanks -

Apologies James
I mistyped. It should be
=SUMPRODUCT(--($B$2:$B$5="Orange"),--($C$2:$C$5="Blue"),$A$2:$A$5)
Ranges must be of equal size in sumproduct. I typed a 1 instead of 2 for the
range in column A and I typed "Oranges" instead of "Orange" for the
criterion in column B.
Must be time to get the coffee pot brewing again!!!

Sum product is not working..... coming up with "0".
Any other ideas?

Hi James
One way
=SUMPRODUCT(--($B$2:$B$5="Oranges"),--($C$2:$C$5="Blue"),$A$1:$A$5)

Hi,
I want to do a SUMIF but on more than one condition. For example:
A B C
3 Apple Green
4 Orange Blue
4 Pear Yellow
5 Orange Blue
6 Orange Red
I want to sum the amounts in column A, based on column B and C. In this
case, sum the amounts in column A for Oranges in column B and Blue in Column
C.
Any help would be appreciated.
James
