Please teach your newsreader some habits; it now quoted my message 
comprensively, down to the signature, without marking quotations, and 
placed your text inside my sig!

Anyway, my crystal ball says that your script code is in your <head>, so 
it will be executed before the browser has read the <body>, so it does 
not know any id attribute values.

The simple (though not most elegant) fix is to place the <script> 
element at the very end of the <body>, i.e. right before the end tag 
</body>.

Well, it *could* be something else, too, like using id="Elem0" instead 
of id="elem0".

Please post a self-contained testable example or URL for such a thing, 
if further help is needed.
