Does setInterval actually work?

1

Ok ive taken my previous post and am just focusing on the setInterval

Why does this example not work???

var numberOfTimes:Number = 0;
var checkInterval:Number = 0;
this.clearInterval(checkInterval);
this.checkInterval = setInterval(watchMyInterval, 100);

function watchMyInterval()
{[INDENT] trace(numberOfTimes);[INDENT] if (numberOfTimes == 5)
{[INDENT] this.clearInterval(checkInterval);
trace(“this.clearInterval(checkInterval);”);
[/INDENT]}
[/INDENT]numberOfTimes++;
[/INDENT]}
