Figured this would be an easy answer but boy was I wrong. It seems like when you look at footer questions, DREL is not returning the selected index - it will always return the full array.
%a[Paintings][0] or %e[Rooms][0][%a[Paintings]] returns 
It should return 15, but apparently not. I did confirm it returns an actual array by adding a delimiter
%a[Paintings][0][, ] returns:
So it's not just returning a string.
After a ton of experimentation I was able to get an array that is accessible by index.
I found that each CHILD section contains the footer question data for the parent section it belongs to - and that can be accessed by index.
%e[Parent][INDEX][%e[Child][0][%a[Question][0]]]
OR
%e[Rooms][0][%e[Walls][0][%a[Paintings][0]]]
This will return
The [Rooms] index is the one you need to change to get values for each room.
%e[Rooms][1][%e[Walls][0][%a[Paintings][0]]] will return:
Paintings must have an index but it doesn't matter what index you give it. The walls index can be anything up to the number of Walls in that Room, but they are all the same value, so 0 works.
I'm guessing it's just a bug with the DREL engine not recognizing the index provided. %a[Paintings][0] and/or %e[Rooms][0][%a[Paintings]] should just work.
Hope this helps and/or restores your will to live.
