This will work for the example you've provided

Range("B35").FormulaR1C1 = "=SUM(R[-27]C:R[-1]C)"

I have a macro that pulls a lot of text files and creates one Excel file.
I
want the macro to insert SUM formulas into various places in the Excel
file.
Could someone give me the VBA code to enter a SUM formula that calculates
the
sum of a range that starts in row 8 and ends in 1 row up from where I am
putting the formula. Example - if I am putting the formula in cell B36 I
want the formula to SUM the range B8:B35. The starting row B8 will always
be
the same but the ending row B35 will vary.

Thanks,
Bill Horton
