=SUM(INDIRECT("A1:A"&COUNTA(A:A)))

I think INDIRECT is the function you are looking for. INDIRECT returns cell
reference specified by a text string. COUNT counts the number of numbers in
a range, COUNTA counts the number of nonempty cells in a range. The & is how
you add text strings together. If this doesn't help, I would suggest giving
actual numbers and results you want.

Hi,

I have a table with a certain number of rows. I don't know how many rows
there are in the table. I can make a data cell that holds the number of cells
in a particular column.

My question is this - Can I then use this figure to make a range to be able
to use inside other formulas in the worksheet?

For instance, the data cell works out there's 743 valid rows in the sheet.
Can I then use this to make a formula in another cell?

I want to get my formula (SUMPRODUCT) which doesn't accept shorthand for the
column ($C:$C) be flexible enough to cope with people adding extra values in
which need to be incorporated into the formula :-)

Thanks
George
