Sorry for posting this again, previous posting of it never got a
response from anybody and I need to get it solved.

I have a macro that adds new rows and copies formulas to these new
rows, I need to make my totals update to include all the new rows, but
the number of rows added is not static

This is what i have for trying to update the formulas when new rows are
added:
With Worksheets("Data")
..Cells(.UsedRange.Rows.Count, 8).FormulaR1C1 = "=SUM(H2:" & _
..Cells((.UsedRange.Rows.Count - 1), 8) & ")"

..Cells(.UsedRange.Rows.Count, 9).FormulaR1C1 = "=SUM(I2:" & _
..Cells((.UsedRange.Rows.Count - 1), 9) & ")"

..Cells(.UsedRange.Rows.Count, 10).FormulaR1C1 = "=SUM(J2:" & _
..Cells((.UsedRange.Rows.Count - 1), 10) & ") +" _
& .Cells(.UsedRange.Rows.Count, 6).Value

End With

Obviously, it doesn't work as submitted. I'm pretty sure the problem is
in the formula, specifically, when I try to reference the new range i
want to work with. I have an idea of what the problem is, I just can't
for the life of me figure out how to change it to make it work properly

I would also like to make these formulas instead only display the sum
of the visible rows (on the last formula, i would also like it to only
add the cell in column 6 if all the rows are visible, note there is a
column hidden that will always remain hidden)

Subtotal will not work because i'm not using filters when the rows are
hidden

thanks for the help everybody, you've all been great with every
question i've asked in the past
