Hi Martin,
(Disclaimer: I'm really new at jQuery, though not at DOM scripting.)
It sounds like you're saying that this line:
> var $selected = $(this).children("th.name");
...isn't finding any matching elements and that that's why you can't
find the <b> child of the <th>. What's the context in which you're
executing that line? Some event handler? If so, on what element? It
would have to be the immediate parent of the <th> (e.g., a <tr>) for
it to find it, since recall that #children finds only _direct_
children of the context.
With a bit more context (no pun!) we can probably figure it out, if
the above isn't helpful.
FWIW,
