Sumproduct query

[Scrunch]

Please could someone help me with a SUMPRODUCT formula? I have the following
data:
A B C
1 Window Summer Winter
2 W1 20 4
3 W2 15 1
4 W3
5 W4 8 3
6 W5 8 2
7 W6 8 1
8 W7 0 0

I need a formula that will count the number of windows with with EITHER a
summer value <10 OR a winter value <2. It should count zeros but not blank
cells.

In the above example the answer should be 5.

I hope someone can help! Thanks

A helper column is easier:

In cell D2 enter:
=OR((B2<10),C2<2)*NOT(OR((B2=""),(C2=""))) and copy down to see:

Window Summer Winter
W1 20 4 0
W2 15 1 1
W3 0
W4 8 3 1
W5 8 2 1
W6 8 1 1
W7 0 0 1

Then just =SUM(D) to get your 5

Try:

=SUMPRODUCT(((B2:B8<10)*(B2:B8<>""))+((C2:C8<2)*(C2:C8<>"")))

But this returns 7 not 5: B5, B6, B7, B8, C3, C7 & C8

As Gary"s Student's solution shows, you don't want to count duplicates - go
with his solution.

This SUMPRODUCT() formula may do what you want:

=SUMPRODUCT(((B2:B8<10)+(C2:C8<2)>0)-((B2:B8="")*(C2:C8="")))

It is also tolerant of a value in one Column and a blank in the second one
if that could be a condition.

Another option:

=SUM((B2:B8<10)*(B2:B8<>"")+(C2:C8<2)*(B2:B8>=10)*(C2:C8<>""))

Enter with CTRL+SHIFT+ENTER because this is an array formula.

=SUM((B2:B8<10)*(B2:B8<>"")+(C2:C8<2)*(B2:B8>=10)*(C2:C8<>""))

Enter with CTRL+SHIFT+ENTER because this is an array formula.

Or, better yet...

=SUM(OR((B3:B9<10),(C3:C9<2))*(B3:B9<>"")*(C3:C9<>""))

 

[Sandy Mann]

Or, better yet...

=SUM(OR((B3:B9<10),(C3:C9<2))*(B3:B9<>"")*(C3:C9<>""))

If the OP's data could have data that meets the criteria in one Column and a
blank in the other then your original formual is better because this one
fails to count that item.

Thanks to all three of you that have posted. You've been a great help.

My data shouldn't have a blank on one column and not in the other but all
your posts have proved very helpful.

Cheers
