conditional sum across columns

[JV0710]

Hi

Please can I get some help with a formula for this query:

On my Sheet I have in Row3 ( from A3 ), headings for months and weeks - so in A3 I have "January" and in B3 I have - week1, in c3 - week2, . . . in f3 - February, g3 -week1 etc

I row 4, I have values in the week columns adding up the month columns.

In A1 I have a number = 8

see example:

Book1
	A	B	C	D	E	F	G	H	I	J	K	L	M
1	8
2
3	January	w	w	w	w	February	w	w	w	w	March	w	w
4	40	10	10	10	10	40	10	10	10	10	50	10	10
Sheet1

I B6 I want to sum the next 8 ( value in A1 ) weeks data from C6

something like Sumproduct(--(left(C3:dd3)="w")*(c4:dd4)) but only for the next 8 instances of "weeks"

If the value in A1 changes to 5 the it must sum the next 5 weeks data etc

I hope that makes sense

Thank you

Presumably you want to define both the number of weeks and the starting point? I also presume that you cannot have the data rearranged as this would be more sensible route. Can the "w" cells be replaced with dates?

Hi StuLux

Thanks for the reply

The headings in row 3 are for the full twelve months of the year with their weeks.

I Cell b6 I want to sum the 8 weeks' values in row 4, in cell c6, I want to sum the next 8 weeks' values in row 4 etc

Unfortunately the "w" cells cannot be replaced with dates and I cannot change the layout of the sheet

I would use the SUMIF and OFFSET function for this, eg.

=SUMIF(B3:OFFSET(B3,0,A1-1),"w",B4:OFFSET(B4,0,A1-1))

I B6 I want to sum the next 8 ( value in A1 ) weeks data from C6

something like Sumproduct(--(left(C3:dd3)="w")*(c4:dd4)) but only for the next 8 instances of "weeks"

If the value in A1 changes to 5 the it must sum the next 5 weeks data etc

I hope that makes sense

Thank you

Try this...

Book1
	B	C	D	E	F	G	H	I	J	K	L	M	N	O	P	Q	R	S
3	W	W	W	W	_	W	W	W	W	_	_	W	W	_	W	W	W	W
4	77	36	13	36	91	59	95	72	43	94	62	99	27	8	5	9	17	69
Sheet1

Array entered**:

=SUM(IF(COLUMN(B3:S3)<=SMALL(IF(B3:S3="w",COLUMN(B3:S3)),A1),IF(B3:S3="w",B4:S4)))

** array formulas need to be entered using the key combination of CTRL,SHIFT,ENTER (not just ENTER). Hold down both the CTRL key and the SHIFT key then hit ENTER.

If the number in A1 is greater than the number of W's in the range then you'll get an error.

What about using a "helper" row (say row 7) where you could have the week commencing or week ending dates, without this I think this will be a struggle as the formual needs to cope with 4/5 week months. I'm thinking of a row that containing dates so that your formula can look between a min and max dates (with a range of A1 X 7 days).

Great answer - Looks like this works to me, one small enhacement would be to add in an IF staement so that for the monthly summary numbers there is no figure showing e.g.

=IF(B3<>"w","",SUM(IF(COLUMN(B3:S3)<=SMALL(IF(B3:S3="w",COLUMN(B3:S3)),$A$1),IF(B3:S3="w",B4:S4))))

CSE formula.

I would use the SUMIF and OFFSET function for this, eg.

=SUMIF(B3:OFFSET(B3,0,A1-1),"w",B4:OFFSET(B4,0,A1-1))

I don't think that'll work.

You're not counting the number of w's based on the entry in cell A1. You're simply offsetting the range.

It worked for me, in testing, as it streches the range to suit A1

Try it on the sample data I posted.
