Countdown Timer Question

[Papajo]

This timer counts down from 5 and stops at 0, is there anyway to loop it
so it will start the count down again? plus could the amount of times it
loops be set?
*******Thank you, Joe

var iCountStart = 5;
var loopCountStart = 3;
var iCount;
var loopCount;
var to;

function startCountdown(start) {
if (start) {
if (to) {
clearTimeout(to);
}
loopCount = loopCountStart;
iCount = iCountStart;
}
if (loopCount > 0) {
window.status = " "+iCount+" ";
if (--iCount < 0) {
loopCount--;
iCount = iCountStart;
}
to = setTimeout('startCountdown(false)', 1000);
}
}
<input type="button" onClick="startCountdown(true)" value="Start">
