I've long since swallowed my pride on this one and just basically need a
dumbed down explanation of the "criteria" portion of this expression.
DSum («expr», «domain», «criteria»)

The simplest explanation I can give you of the 3 arguments is this one:

It explains DLookup(). Follow that through. Once you understand it, DSum()
is exactly the same, except it sums the first field instead of just
returning the first match.
