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 |

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

#+results: totals
