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,
