I think actions may be the answer for your original problem, which was
to distinguish the two positions (so you created the geoloc1 and geoloc2
rules). An action like this:
{ $return = { item1 => $item[1], item2 => $item[3] }; }
would give you back a hash with the entries for your matched items named
appropriately. I don't know why you had subrule problems, sorry.
You could also consider the <leftop> command, which could set up
"A and B and C" parsing for you, unlike your current rules which only
accomodate one "and". You can use actions again to return the right
things by name.
Hope this helps.
