Oh, dam. Turns out it doesn’t work without the “myaxis” 
So using “[#it.children.at(0)]” inside the show rule actually displays all the numbers correctly, but it still has the type content. Oddly enough, “[#it.children.at(0).fields()]” displays an empty dictionary (:)
Because the dictionary is empty, the to-string function I implemented just returns an empty string.
So at this point I don’t really know how to continue. The content has text in it, but I have no idea where to find it…
