This comes up all the time. See this thread:
- http://lists.gnu.org/archive/html/emacs-orgmode/2012-07/msg00323.html

The key is to put it 1) before results (as you've done) and 2) to use
a named source block (with #+name: foo above your babel code) so that
Org knows what the results block actually is. Otherwise, as you
currently have it, if you re-run the babel block, you'll keep the
results section you already have and it will spit out another one
below it since it no longer recognizes that the babel block and
current, modified results block go together.


Good luck,
John
