Ok,,but maybe more red herrings would be good?

The Balkan countries group should allow just 'countries' because that is what I put and it said it was incorrect. Because they are countries. Why is 381 and Dinar related to Serbia?
I have never watched frozen and I got it right! But I have heard of 'Let It Go' not the other three though.

Hello Thinks...the dinar is the currency of Serbia and 381 is the country's telephone code I believe.hope that helps.

Thanks Wiz . Explanations make grids so much more interesting.

Oh No, not frozen, AH!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
