Hey,  
I’m having an issue with setInterval/clearInterval when it comes to dealing with objects. Take this example:

[AS]   
MovieClip.prototype.setCount = function(numToCount){  
this.interval = new Object();  
this.interval.count = 0;  
this.interval.countUp = function(numToCount) {  
this.count++;  
trace(this.count);  
if(this.interval.count == numToCount){  
clearInterval(this.countUp);  
}  
};  
setInterval(this.interval, “countUp”, 100, numToCount);  
};

myMc.setCount(3);  
[/AS]

Why does clearInterval not stop the interval? Does clearInterval not work when called inside a setInterval? Am I doing something wrong? How do I get it to delete the interval when it reaches a certain count?

Thanks again!
