Problem removing Objects from the stage in Flash CS4 (AS3.0)

Question

I have a problem with this code:
this.addEventListener(Event.ENTER_FRAME, vanish);
function vanish(event:Event):void{
     if(character_mc.hitTestObject(vanish_mc)){
          vanish_mc.parent.removeChild(vanish_mc);
There are two overlapping objects on my stage: character_mc and vanish_mc.
As soon as i start the scene[Ctrl+Enter] vanish_mc is VISUALLY removed. But the code still sees a collision somehow. How can i Entirely remove the object vanish_mc?
Thank you for help and advice.

Answer 1

Ah I think the problem is what my problem not which I proposed, my bad I was trying to keep it simple.
the remove code in my problem actually looks like this:
if(character_mc.hitTestObject(this["dollar_mc_"+String(i)])){
     removeChild(this["dollar_mc_"+String(i)]);
I wanted it to be that way so I could add infinite "dollar_mc_" ' s without writing myself to death with code and or getting confused.
Imagine it like a game where a character it picking up dollars, which would disappear once they intersect.
And that exactly is what gives me that argument.
Do you know a way i could write this code, or do you suggest to leave it that way...because it does run and work im just getting this argument while debugging.
Thank you for all the help~
