[jQuery] appendingTo a just created element

Hi All,

I'm fairly new to jQuery so I apologize if I'm missing something
straightforward but doing this:

$('<div/>')
.attr('id', 'someID')
.insertBefore(elm);
$('<p/>')
.appendTo('someID');

Seems to give me errors. If I change "appendTo('someID')" to a
different element's ID, it works fine, so I get the feeling that it
can't append to the just-created div. Is this not the case? What
should I do to move forward?

Thanks for the help!
