Hi Mal,
Yes, it must be the actual name of the sheets. In this example the sheet
named Mice is the first sheet and Cats is the 28th sheet.
=SUM(Mice:Cats!F1)
A quick way to make this formula is to type =SUM( into the cell you want the
totals in and then select the first sheet and with the shift key held down
select the last sheet. All the sheet tabs should be highlighted. Release
the shift key and click on the cell you want to sum. Now add the ) to the
formula and hit enter. This assumes you are totaling 28 sheets and the
formula is on a sheet other than the 28. 29 sheets in all.
If you are totaling on the first of 28 sheets type in =SUM( and hold down
the shift key and select the last sheet and then the cell and then the ) and
then enter.
HTH
Regards,
Howard
