function watchTime() {

i try to call function startCron() inside resetCron(), but didnt work
on reset, you set the inner text of
it replaces minutes, second, and hundredths span. because of that when you want to start the stopwatch again startCron does not find minutes, second, and hundredths span. that's why it gives an error.
replace document.getElementById('watch').innerText='00:00:00'; with
and one more thing, disable the start button when the watch is started and enable it when the watch is paused or reset.
