Removing children with conditional statements help!

I have a movie that need to remove a child in order to load another. This will be done through the use of a button. Works fine, yet I need to remove other children with the same button. Example… I click the button, the child is removed and we jump to another spot on the timeline. Now I choose another section of the movie. When clicking the same button I need the to code to recognize that this is a different child and remove it. I was thinking a switch statement would be the best route, yet I am not versed enough within as3 to know for sure and what the exact syntax is. Can someone point me in the right direction?
The code below is the code used to remove child:

backTest.addEventListener(MouseEvent.CLICK, Backer);
function Backer(event:MouseEvent):void
{
gotoAndPlay(“skip”);
removeChild(ArchSkipLoader);
player.stop();
govplayer.stop();
}

Thanks for any available help!
