Cannot clearInterval in class

programming flash

Hi:

I have just started working with classes and am having trouble using setInterval/clearInterval in the class. I am sure my scoping is incorrect but I am not sure how to fix it. My problem (simplified) is below:

class myClass extends MovieClip {
var loopImage:Number

function myFunc1(){
loopImage = setInterval(cycleImages, 4500);

}

function myFunc2(){
clearInterval(loopImage);
}

function cycleImages(){
//irrelevent whats in here
}

}

Bascially, how do I set up my interval so that when “myFunc2” is called, loopImage is not undefined and it is able to clear the interval.

Thanks in advance.
