You appear to be confusing lists and arrays. The arrayname[key] notation has no
significance for lists, which is why this example doesn't work as you expect.
Remember, arrays are like hashmaps, and can store key => value pairs. They are
defined like this:
"arrayname[key1]" => "value1";
Lists are one dimension only. Lists are useful to store all the keys in an
array ... Using indices. :-)
Hope this helps,
