That's no longer true as of HTML5, which in this case is just documenting 
what browsers already did:
http://www.w3.org/TR/html5/elements.html#the-id-attribute

It *was* true for HTML4, but browsers didn't care in terms of 
document.getElementById and such.

Note that it's still true for CSS (#1 is an invalid selector), and browsers 
*do* care about that (e.g., with querySelectorAll and such):
http://www.w3.org/TR/CSS21/syndata.html#value-def-identifier

So while HTML5 is very lax, if you're ever going to use CSS selectors to 
refer to the element, best to stick to the more restrictive CSS rules.

$(cbValue).checked returns boolean (true|false) and you compare it to 
string:


if( cbState == checked  )

simply

strState = (cbState == true) ? checked : unchecked;

Dave, you're a gentleman and a scholar...

The id was irrelevant because in the original pass I was passing in
this.checked but then someone suggested we allow them to change the mode as
well so then I couldn't use this.checked with an onchange fired via a
select and by then it was wy to late into the wee hours to see what
was wrong.

Thanks!
