ActionScript 2, attachMovie

Hey, people!

I've got a small issue with attachMovie.

I've got an array with references to movie clips which I want to place at random locations on the scene.

Here is my function:

function randomize(target_array){
    top_y = 87;
    bottom_y = 296;
    
    left_x_range = 16;
    right_x_range = 220;
    
    left_x_range_second = 305;
    right_x_range_second = 535;
    
    for(i = 0; i < target_array.length; i++){
        var mc = target_array;
        trace(mc);
        
        mc_clothes_holder.attachMovie(mc, mc, mc_clothes_holder.getNextHighestDepth());
        
        currY = Math.floor(Math.random() * (1 + bottom_y - top_y)) + top_y;
        
        if(i%2 != 0){
            currX = Math.floor(Math.random() * (1 + right_x_range - left_x_range)) + left_x_range;
            mc_clothes_holder.mc._x = currX;
            mc_clothes_holder.mc._y = currY;            
        }else{
            currX = Math.floor(Math.random() * (1 + right_x_range_second - left_x_range_second)) + left_x_range_second;
            mc_clothes_holder.mc._x = currX;
            mc_clothes_holder.mc._y = currY;
            
            trace(mc_clothes_holder.mc);
        }
    }
}

The thing here is that the trace of "mc" in the beginning returns the correct movie clip reference, but "mc_clothes_holder.mc" after the attachMovie returns "undefined".

Does anyone have any idea why this doesn't work? What have I done wrong?

Thanks!
