Hi Giuseppe,

In REBOL, variables don't "contain" values, they reference them; hence
Anton's pointer metaphor. This is how REBOL can be dynamic, yet
strongly typed. Values have type; variables don't, they can refer to
anything.

It will work on the last value in a block if that value, itself, is a
series. If the last value in SITES was, say, $100.00 or 'testing, it
would fail.
Even better than assuming, sprinkle some print statements in there.
See what the values are, what type they are, whether they're EQUAL? or
the SAME?, etc.
