Clearing the stage (in preparation for the next level)

[senshi sentou]

Hey everyone,

Me again. I got the level I was working on to work correctly, but now a new problem has risen.
I'm trying to clear the stage of all objects on there, so that I can show the next part of the game (albeit in a new frame, or by adding new MCs onto the stage).
Basically, I have a loop checking to see whether or not the player has reached the end of the current level, as well as checking if the stage has been cleared yet:

else if((stop_all == true)&&(empty_stage == false)){
	cleanup();
}

The 'else' is definitely needed. stop_all is set to true as soon as the player reaches the end of the level, empty_stage is initially set to false.

function cleanup():void{

for (var si=0; si<stage.numChildren; si++){
    children.push(stage.getChildAt(si));
}
for (si=0; si<children.length; si++){
    children[si].parent.removeChild(children[si]);
	}
	empty_stage = true;
	gotoAndPlay("bonusgame");
	//setEnd();
}

function setEnd():void{
	endtext.x = 500;
	endtext.y = 500;
	endtext.text = ("Gefeliciteerd!!Je hebt een topsnelheid van ");
	addChild(endtext);
	trace(endtext.text); // This one works.
}

All of the needed variables are declared, but the object just won't show up (other objects won't either). However, I can still trace out endtext's text, x and y, alpha and other properties.

I've also tried a gotoAndPlay("nextPartOfGame") instead of the setEnd() function, but to no avail.

Again, any help would be much appreciated.
