It's not possible as the conditions you specify set up a circular reference; in
addition, you cannot have both the number '2' and a formula in the same cell
(column C).

If you would care to purt your formulas in other than C1:C3, you could use the
formula:

=SUM(OFFSET(B1,,,,A1))

for Row 1 and copy/drag down as needed.

If you want something else, or really want to use a circular reference, I'd
need more details of exactly what you are trying to accomplish.
