Hello,

i have a STRANGE problem with 2d arrays in flash. Trying to create matrix of squares, i used this code:

```auto
var nCol:Number = 8;
var nRows:Number = 6;
var nBlockW:Number = 100; // _width and _height size of block in pixels

var aArray:Array = [[],[]]; // 2-dimensional array declaration
    
for(var i=0; i<nCol; i++){
    for(var j=0; j<nRows; j++){
        var mc = this.attachMovie("mcBlock", "mcBlock_"+i+"_"+j, this.getNextHighestDepth(),{_x:i*nBlockW, _y:j*nBlockW});
        aArray*[j] = mc; // store path to block mc in array
        trace(aArray*[j]) // trace stored
    }
}

```

Now what happens is, that all mcs get properly attached, and displayed BUT array is incorrectly filled: trace(aArray\*[j]) traces:

```auto
_level0.mcMask.mcBlock_0_0
_level0.mcMask.mcBlock_0_1
_level0.mcMask.mcBlock_0_2
_level0.mcMask.mcBlock_0_3
_level0.mcMask.mcBlock_0_4
_level0.mcMask.mcBlock_0_5
_level0.mcMask.mcBlock_1_0
_level0.mcMask.mcBlock_1_1
_level0.mcMask.mcBlock_1_2
_level0.mcMask.mcBlock_1_3
_level0.mcMask.mcBlock_1_4
_level0.mcMask.mcBlock_1_5

🙂 sorry for the flood. So as you can see, first 2 iterations of “higher” cycle mc creation are nicely stored, while the rest is not so lucky.

Any ideas how to fix this? Thank you.
