It seems there is no way to stop you from encountering the "chicken
and egg" problem!

Normal (:pagelist:) allows PTVs inside as values.
Normal markup expressions and PTVs do not allow (:pagelist:) inside
them as values.
With the {(pagelist )} markup expression we can  use PTVs
inside it, but it does not allow PTVs as values inside itself.

The only way to go with the (sumdata (pagelist...) data=...) expression
I can think of is not to use PTVs in the inner (pagelist) (because
they don't work), but use the $:Dept and $:Month PTVs inside the
sumdata function, to filter a larger pagelist.
