Found it.

In the central Template loop

[% FOREACH choice IN data.$type.$company.$name.choice_list %]
     [% data.$type.$company.$name.choice_list.$choice %]<br>
[% END %]
[download]

of course, since we're dealing in this loop with an array and not a hash, 'choice' pulls out the value stored in the array, not the hash key like in the previous loops. I was referring to the index of the array element with the value in the elements - which go from 1 to 6, not 0 to 5.

The correct format was

[% FOREACH choice IN data.$type.$company.$name.choice_list %]
     [% choice %]<br>
[% END %]

which gives me the correct output.

Thanks.
