collection, and an
id, what would you do with that to try and find a

idvariable and you'll be using it in the way that will be a general-purpose solution. But, for the sake of argument, you are using one of the values. So let's move on to the next thing. If you have this construct:
collection["1245"]- what does that allow you to access within the data?
