automated continuous adding

[highbeef]

Hi
i have 2 columns. one column outgoings, one column incomings.
at the top of the page i also have subtotals for these columns.
The problem is that i have to keep changing the cell numbers of th
subtotals because new values are added to the columns and therefor
make them longer.
How do i automate this procedure??

Any help would be greatly appreciated

How about just using extremely large rows?

=subtotal(3,c3:c65536)
