Ah! Thanks. Got it totally working now!

One other minor thing- would it be possible for the the strings inside
'France' => ['Rennes', 'Paris']
to be variables instead?

i.e. instead of France= those two I earlier have a 'enter country name' 
and 'enter city 1', 'enter city 2',etc...


Off the top of my head I think there may be some sort of symbol you'd 
put before nation to show it is a actual stored string but I can't 
remember what it was...
