Hi
you may provide some more details about your data structure. e.g. post some
example rows of data as plain text

I have a spreadsheet set up which feed in monthly figures eg in jan figures
are put in under the jan heading. in feb figures are put in under the feb
heading etc. at the bottom of the sheet is a total for all months, but need
to write a formula to add only two columns if the month is feb or 10 columns
if month is october.

Hi
what I want to know is soem exact details (cell references). e.g.
- in which sells is the month name (in row 1, etc.)
- which cells do you want to sum

As said: just post some example data as plain text

Hi
The Supplier Name is in col B, the month number is in C8 of sheet 'Summary'
and the data it needs to add is in the sheet 'turnover' with the Supplier
name in col A and the months starting with Jan in the following colums ie Jan
in B, Feb in C etc with the turnover per month in the relative rows for the
Supplier. What I want the formula to do is to lookup a Supplier name in
Turnover (col A) that is in the Summary Sheet (col B), read the no of periods
(col C in Summary) and then sum that no of columns in the Turnover sheet
pertaining to the Supplier.

Hi
now that helps
try the following formula
=SUMIF('turnover'!$A$1:$A$1000,$B8,OFFSET('turnover'!$A$1:$A$1000,0,MATCH($C8,'turnover'!$B$1:$N$1,0)))

Hi
Can't get the formula to work, keep getting N/A even though there is data to
sum. Is it possible that I need to have numerical column headings as the
'MATCH' part of the formula seems to be looking for a number to match to.

Hi
the value that is in C8 has to be as well in the range B1:N1 on your
turnover sheet. e.g.
C8: Mar
B1:N1:
Jan - Feb - Mar - Apr - ...

Hi Frank

Still can't get this formula to work. It is referencing the column no and
bring the data in that column but is not adding the colums up to that column
no. Ir if if C8 = 9 and the value in col 9 is 4211.00, then the formula is
showing 4211 and not the sum of all the columns up to column 9.
