Hi

Try
=SUM(INDIRECT("A"&X1&":F"&X2))

Where X1 and X2 are the cell references containing the formulae that
calculate the row numbers required

If I use the function =SUM(A#:F#), I will get a sum for a matrix. Now I
would
like to substitute the #'s with formulas which calculate the row for each
column (A,F). Thereafter, I would like to copy the function with the
formulas
to other cells.
