hey thanks Hassan, yeah it does help, but I'm getting a little 
worried...  I'm trying to append or replace a text node:

<input type="checkbox" "id="qsfcontrol" onClick="toggle(this)" />Tick 
the box to ignore these search criteria

if I understand you correctly, the text "Tick the box to ignore these 
search criteria" is not a child of 'qsfcontrol' which would explain why 
when I originally tried replaceChild(), nothing at all happened, no 
errors, nothing.  Is it then a sibling?

checking the box disables part of the form (nice idea I got from Nelson 
in an earlier thread) and I want to toggle the text next to the box. 
 the form isn't in a table, so the box and the text aren't separable by 
<td>, so I'm wondering what is the semantically correct way to structure 
the message next to the text box.

Of course I could put the text in a named <p>, <span>, <li> etc, and use 
replaceChild() on that text node but then I have to assign a special 
class to it which I want to avoid. Its going to be part of a very large 
site, and I want my CSS to stick with type selectors as much as 
possible, rather than having a ton of classes all over the place as well.
