Yes, and it's a nice addition to your debugging repertoire.

Do you have the Microsoft Script Debugger installed? Because it's
halting on this line:

	secs = (osec.innerHTML)-0;

:: proving that even IE, in its secret heart of hearts, knows that
innerHTML is the TOOL OF SATAN  :-)

OK, just ignore that; here's the fix:

function decrement()
{
	var secs = 0;
	var mins = 0;
	var hrs  = 0;
	var days = 0;
	
// get thee behind me, innerHTML! :-)  secs = (osec.innerHTML)-0;

	secs = parseInt(osec.firstChild.nodeValue);
	mins = parseInt(omin.firstChild.nodeValue);
	hrs =  parseInt(ohrs.firstChild.nodeValue);
	days = parseInt(oday.firstChild.nodeValue);
...

I'd fix the setValue() to not use innerHTML, too, but that's me. And
it works on Safari, but not IE5.2/Mac. Sigh. Big surprise. I'll try
to take a look at that later but I've gotta run do something else now.

HTH!
