If you put this formula in any cell of any sheet, it will SUM the contents of
cells A1 through A52 on Sheet 1............

=SUM(Sheet1!A1:Sheet1!A52)

Thanks for suggestion but unforunately it does not solve problem. If I am in
week20 of the 2005 the cumulative figure in my summary is the sum of cells
a1: a20 on sheet 1 and so on down the 50 products I monitor.
On sheet 2004 my summary is the same product a1:a20 and so on for the five
other sheets
What I am trying to do is find a way so that when i get to Week 21 and I
change the formula in the summary to a1:a21 it will automatically change the
formula on Sheet 2004 to a1:a21 and so on through the other sheets. At the
moment I am changing the formula on the first line of the summary and then
copy/pasting the change down all fifty products and then repeating the proces
on each of the other 10 pages.
It would be great to find a way of doing only the current year sheet and
having all the other sheets update formulas at the same time

In any cell on any worksheet you can enter this formula and it will return
the contents of Cell A1 from Sheet 1.

=Sheet1!A1

Change the SheetName and Cell address to suit your needs.

Each week I enter sales 4 products in sheet1.With a column per week and row
per product. Below this I have a cumulative total 2date for each product.
Sheets 2-6 have results 4 each of the previous 5 years and also a similar
table showing the cumulative total 2date.Sheets 7 -11 compare performance
between successive years.Sheet,12, shows results 2date for each product &
each of the 6 years.
At present I enter current figures in sheet 1,then go to sheets2-6 and alter
the sum formula for each row to cover the same number of weeks as on sheet 1.
Simlarly I have to go to the comparisions sheets 7-11 to change the sum
formula there. Is there a way I can alter the row sum formula on sheet 1 and
it automatically alter the corresponding formula on all the other sheets?
save me a lot of time!
