ActionScript 3.0 :: Code Used To Load A MiniMap (which Changes Size)?

Below is my code used to load a MiniMap (which changes size)My problem is trying to update the level i have two buttons on the stage for next and previous.I Cannot update the level without the old set of minimap tiles staying there and if i try to remove the MiniMap container it spits out errors or a trace will return multiple times when i only expect it to return once. have been stuck at this point for the past 3 days.I can zip up the project. its only a small class and 6txt files if needed.

ActionScript Code:
function loadMap():void {//fucntion for loading the maps-
var l1:level1 = new level1();

[code].....
