Hi list,
Formulas reference in a long table are very easy corrupted by manually
inserting. so, I think, refer using name instead of num. is better.
but how to refer the rows by name?
For example,
|---+------+---------+--------+---------+------|
| ! | date | amount | item | account | note |
| | date | amount | item | account | note |
|---+------+---------+--------+---------+------|
| _ | | bamount | | | |
| | | 12 | lunch | pocket | |
| | | 59 | dinner | pocket | |
| ^ | | eamount | | | |
|---+------+---------+--------+---------+------|
| _ | | total | | | |
| # | | #ERROR | | | |
|---+------+---------+--------+---------+------|
#+TBLFM: $total=vsum($bamount..$eamount);%.2f
I'd expected $bamount..$eamount is the range of @II$amount..@III$amount, but
it's not. $bamount and $eamount are epxanded to the values too early.

I see the problem you have.
To my understanding, field names like "bamount" and "eamount" refer to
the _value_ of the above/below field, not to the _position_. So when
the formula is computed, these names are replaced by values, not by
position -- hence the result you have.
I'm not sure this is by design.
Maybe Carsten can tell more, and/or have a look in this issue when he's
back.
Best,
