Hello Pisco,

What you have here is close, but you shouldn’t be calling dbobject.on('value') twice (it gets called again inside the callback for the first invocation). And since these are realtime data streams, you probably want to work with child_added instead of value anyway.

Reading data from a list is covered here. Check out that doc and our samples for some pointers.

☼, Kato
