Aside to Bastien's help for this issue, a variable that will
prompt you before the formulas are rewritten, consider this:
Most of the time is should be possible to rewrite the formula
in a stable way.  You did not show your example, but from the
formula I would assume that you start the table immediately
with data, without a header line org a horizontal separator line.
If you did, you could do vsum(@I..II) and have a formula that is
stable against row switches.

Hope this helps.
