I want to add another timer which is personal, so the code will have a total of 3 variables for countdown timer which are Lunch, Break and Personal. Please help on this. Thank you very much.

<SCRIPT type=text/javascript>

var t1,t2;
function timedCount(type) {
document.getElementById('mode').value=type;
if (t1state == 0) {
    startCount();
} else {
    stopCount();
}
if    (t1state==0) t1state=1; else t1state=0;
}

Code (markup):

 

I think you may have gotten too complex on something simple, but it's hard to say for sure without seeing what it is you're actually doing here -- more specifically how any of these functions are being called/started either by other scripts (the right way) or in the markup (onevent, the sloppy way)... looks like a good time to start using objects... stop using innerHTML (like we're supposed to), and so forth.

As to a third timer, that should be simple enough -- just make another pair of functions (or better use methods on an object), to handle the start and stop.

THOUGH, if you only need one second granularity, I'd consider using an array of functions or objects and a single timeout handler. Also it's a little odd you have some code that only looks like it should care about being called once a second, that's being called every 600ms... Most unusual.
