Mixing Absolute and Relative Reference in a Formula

[tedd13]

Hello,
I am trying to mix absolute and relative references in a formula. I am
trying to sum a column who's length changes. One time there may be 20 cells
in the column with data and the next time it might have 50.
I know that the data starts in the same place every time, cell A15. I use a
Do Until loop to find the last cell with data in the column. After I find
the last cell in the the column, I move to the next cell down. My total will
go in this cell. I then want to sum the column, starting in cell A15 to
whatever cell is the last one in the column.
I think I need something like SUM(A15,ActiveCell.Offset(-1,0)).....Is
something like that possible?

Dim rng as Range
set rng = cells(rows.count,1).End(xlup).Offset(1,0)
rng.FormulaR1C1 = "=Sum(R15C:R[-1]C)"

or

Range("A15").End(xldown).Offset(1,0).formulaR1C1 = _
"=Sum(R15C:R[-1]C)"

If there are no populated cells below your data:

With Range("A" & Rows.Count).End(xlUp)
.Formula = "=SUM(A15:A" & .Row - 1 & ")"
End With

No need to lopp through the cells.

iLastRow = Cells(Rows.Count,"A").End(xlUp).Row
Cells(iLastRow+1,"A").Formula = "=SUM(A15:A" & iLastRow & ")"

wouldn't it be

With Range("A" & Rows.Count).End(xlUp)(2)
.Formula = "=SUM(A15:A" & .Row - 1 & ")"
End With

Yup - misread...thanks for the correction.
