Hi there,

It looks like you've changed the for loop from what was already in the challenge code. You want to leave this line intact:

for (key, value) in world {

The dictionary is made up of keys and values, so we have to address both. For example, the first item in the array has "BEL" as the key and "Belgium" as the value. The challenge is asking you to populate the arrays with just the country names (which are the values in the dictionary). So what you want to do is switch on the key from each item in the dictionary, and if it matches the right region, append the value to that region's array.

Give it another try and report back :blush:.

Cheers :beers:
