Actionscript 3 :: Re-stacking MovieClips In An Array?

I was trying to make a similar thing with the game SameGame (ie. the block above the removed blocks fall downward). Before trying this with an Array that contains MovieClips, this code worked (tried it with int values). With MovieClips on the array, it seems not working the same way.With int values, example:

popUp(0, 4): Before: 1,2,3,4,5,6,7,8,9,10; After: 1,2,3,4,6,7,8,9,10

But with MovieClips:

popUp(0, 4): Before: 1,2,3,4,5,6,7,8,9,10; After; 1,2,3,4
// Assume the numbers are movieclips XD

Basically, it strips everything else, rather than just the said block >_< Here's the whole method. Basically, two extra arrays juggle the values above the soon-to-be removed value, remove the value, then re-stack it to the original array.

function popUp(col:uint, row:uint)
{
var tempStack:Array = new Array();
var extraStack:Array = new Array();

[code]....
