I am trying to parse the program based on the article above and comments on the link you posted.

> The first occurrence of a variable name defines it as that sum. Subsequent occurrences become the stored value.

With this quote in mind - why is second `SUM` reference replaced with `-138.95` and not `221.81` (stored value) ?

EDIT: Never mind, now I see it's an exception on line 3.
