that's right - it's looking for the id of the object (as a string), not
the actual object itself.

so you need to be passing the id:
    document.getElementById(obj.id).style.display

however, if you've already got your object reference, you don't need to
be using document.getElementById at all

so just this may work in your example:
    obj.style.disply
