different result in spreadsheet tutorial

[Stuart McLean]

Hello,

I am just beginning to learn org-mode's spreadsheet with the tutorial
here: http://orgmode.org/worg/org-tutorials/org-spreadsheet-intro.php

However, when I type C-c C-c on the TBLFM line below




| Student  | Maths | Physics | Mean |
|----------+-------+---------+------|
| Bertrand |    13 |      09 |   11 |
| Henri    |    15 |      14 | 14.5 |
| Arnold   |    17 |      13 |   15 |
|----------+-------+---------+------|
| Means    |    15 |      12 |      |
#+TBLFM: $4=vmean($2..$3)::@5$2=vmean(@2$2..@4$2)::@5$3=vmean(@2$3..@4$3)


I get 13.5 in D5. I assume $4=vmean($2..$3) is being computed for this
row as well. Am I doing something wrong?

Please excuse if this has been covered earlier in the newsgroup

Thanks,

Stuart

Yes, this is how column formulas work.

You can either use field formulas for the three fields, or you can  
overwrite the corner field with

    @5$4=string("")
