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.

Tx

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.
