Hi,

I'm trying to do some simple calculations, but the results are plain
wrong.  I started the minimal example with `emacs -Q -l minimal.emacs
org/minimal.org'.  My Emacs is 24.3 with Org-mode version 8.0-pre
(release_8.0-pre-116-g65cde8 @ /home/ov/p/org-mode/lisp/):

#+TITLE: Nutrition Facts
#+CONSTANTS: b=100 j=4.182

#+TBLNAME: nf
| Product   |   kJ | kcal |
|-----------+------+------|
| Bread     | 1372 |  328 |
| Butter    | 3054 |  730 |
| Marmalade |  926 |  221 |
#+TBLFM: $3=$2/$j;%.0f

Here are some calculations per portion (plain wrong):

| Product   |    g |   kJ | kcal |
|-----------+------+------+------|
| Bread     | 50.6 |  658 |  157 |
| Butter    | 11.5 |  150 |   36 |
| Marmalade | 19.7 |  256 |   61 |
|-----------+------+------+------|
|           |      | 1064 |  254 |
#+TBLFM: $3='(* $2 (/ (org-lookup-first $1 '(remote(nf,@address@hidden)) 
'(remote(nf,@address@hidden))) 100));N%.0f::$4=$3/$j;%.0f::@>$3..$4=vsum(@I..II)

Expected:

| Product   |    g |   kJ | kcal |
|-----------+------+------+------|
| Bread     | 50.6 |  694 |  166 |
| Butter    | 11.5 |  351 |   84 |
| Marmalade | 19.7 |  182 |   44 |
|-----------+------+------+------|
|           |      | 1227 |  294 |
#+TBLFM: $4=$3/$j;%.0f::@>$3..$4=vsum(@I..II)

Using the constant b is also totally wrong:

| Product   |    g | kJ | kcal |
|-----------+------+----+------|
| Bread     | 50.6 |  0 |    0 |
| Butter    | 11.5 |  0 |    0 |
| Marmalade | 19.7 |  0 |    0 |
|-----------+------+----+------|
|           |      |  0 |    0 |
#+TBLFM: $3='(* $2 (/ (org-lookup-first $1 '(remote(nf,@address@hidden)) 
'(remote(nf,@address@hidden))) $b));N%.0f::$4=$3/$j;%.0f::@>$3..$4=vsum(@I..II)

These results are achieved using `C-c C-c' on the first column of the
format line.  If I use `C-u C-c C-c' in the tabel I get different
results *every* time.  E.g. pressing `C-u C-c C-c' three times on the
`B' of `Bread':

| Product   |    g |     kJ |  kcal |
|-----------+------+--------+-------|
| Bread     | 50.6 |  32606 |  7784 |
| Butter    | 11.5 |  59888 | 14297 |
| Marmalade | 19.7 | 110192 | 26306 |
|-----------+------+--------+-------|
|           |      | 202686 | 48387 |
#+TBLFM: $3='(* $2 (/ (org-lookup-first $1 '(remote(nf,@address@hidden)) 
'(remote(nf,@address@hidden))) 100));N%.0f::$4=$3/$j;%.0f::@>$3..$4=vsum(@I..II)

If I go to the end of the format line and press `C-c C-c' I get totally
different results as at the beginning:

| Product   |    g | 1064 |  254 |
|-----------+------+------+------|
| Bread     | 50.6 | 1064 |  254 |
| Butter    | 11.5 | 1470 |  351 |
| Marmalade | 19.7 | 2790 |  666 |
|-----------+------+------+------|
|           |      | 5324 | 1271 |
#+TBLFM: $3='(* $2 (/ (org-lookup-first $1 '(remote(nf,@address@hidden)) 
'(remote(nf,@address@hidden))) 100));N%.0f::$4=$3/$j;%.0f::@>$3..$4=vsum(@I..II)

If I use `M-x org-table-recalculate-buffer-tables' even the headlines
get screwed up.  Am I doing something wrong or are there severe problems
in the spreadsheet mode?

Thanks in advance!
