I'm trying to log my hours in org mode:

```
** Bob Johnson, Bob's SEO
| subject                                       | time                      | minutes | total hours |
|-----------------------------------------------+---------------------------+---------+-------------|

|-----------------------------------------------+---------------------------+---------+-------------|
|                                               |                           |     249 |        4.15 |
#+TBLFM: $4=@0$-1/60::@6$3=vsum(@I..@II)

```

The main problem is the expression above that sums up total hours:

```
@6$3=vsum(@I..@II)

```

Should be something like:

```
@||+1$3=vsum(@I..@II)

```

So that as the spread sheet grows the last item in the second to last column will always sum the total. It doesn't work when I set it this way (and `+II`, and other ways) however.

Any ideas?

Thanks!
