attachMovie

hey guys,

is it possible to to change the value of the alpha setting of an attachedMovie

I have


function attachBk (thisBk, nextBk):Void {
    if (thisBk == undefined) {
        this.attachMovie(nextBk,"bkHolder1", this.getNextHighestDepth());
    }
    else {
        this.attachMovie(nextBk,"bkHolder2", this.getNextHighestDepth());
        this.attachMovie(thisBk,"bkHolder1", this.getNextHighestDepth());
    }
}

When I click a button I want bkHolder1 to fade out but so far I haven’t had any success, I tried doing bkHolder1._alpha = 0 just to see if it would affect it’s property but it didn’t.

any help would be greatly appreciated
