Hi everyone,

I'm trying to get my head around babel and getting info back into a
table.

The below org file tracks expenses and the perl code simply sums them
up.

The code is working but I now want to get the total back into another table.  What I have is not
working can someone tell me what I'm doing wrong here?

Cheers

Bart

* Expenses

#+tblname: expenses
|------------+-----------------------------------+--------|
|       Date | What                              | Amount |
|------------+-----------------------------------+--------|
| 2010-07-26 | Breakfast                         |      5 |
| 2010-07-26 | groceries                         |    8.5 |
| 2010-07-26 | butchers - chicken                |    5.5 |
| 2010-07-27 | umart - video card, kvm, speakers |    136 |

* Code

#+srcname: totals 
#+begin_src perl  :var details=expenses[1:-1]
  my $total = 0;
  foreach my $row  (@$details) {
      $total += @$row[2];
  }
  
return $total;
#+end_src

#+results: totals
: 155



* Totals

| Total | #ERROR |
  #+TBLFM: $2=#+call: totals(details=expenses)

Hi Bart,

You've mixed up #+call and sbe there. sbe is what you want to use in a
table formula; #+call and #+lob are for standalone lines. Here are a few
examples of different ways to do what you're doing. Hopefully they make
things clear.

Dan

--8<---------------cut here---------------start------------->8---

* Totals
** Using a table formula

*** Relying on default argument to totals block
| Total | 155 |
#+TBLFM: $2='(sbe "totals")

*** Providing argument explicitly

The dots are a bug. We'll fix it.

**** version 1
| Total | 155... |
#+TBLFM: $2='(sbe "totals(details=expenses[1:-1])")

**** version 2
| Total | 155... |
#+TBLFM: $2='(sbe "totals" (details "expenses[1:-1]"))


** Using call/lob

#+call and #+lob are synonyms

*** Relying on default argument to totals block

#+call: totals()

#+results: totals()
: 155

or equivalently (it outputs into the same results block):

#+lob: totals()

*** Providing argument explicitly
#+call: totals(details=expenses[1:-1])

#+results: totals(details=expenses[1:-1])
: 155

--8<---------------cut here---------------end--------------->8---

Dan,

Thank you very much for that explanation! 

This makes the whole thing much clearer.

Do you know where the sbe call is documented in the manual?  I couldn't
find it my self.

Thanks again.

Bart

It's documented in the original Worg pages here

http://orgmode.org/worg/org-contrib/babel/intro.php#spreadsheet

but you're right, it looks like that information is completely lacking
from the manual. I've added it as a babel development TODO.

Thanks for pointing that out,

Dan
