loadMovie and then duplicatemovieclip wont work

I just need to load the pic and then duplicate the movieclip...
Anyone knows why I can't???
Please help!


I have this code:
>
> button_btn.onPress = function(){
> ...
> center_32_MC.loadMovie("media/bg/"+x+".jpg");// loads the pic properly
> tile=
> _root['tile']._root.Ntiles+'_mc';
> tile.loadMovie("media/bg/"+x+".jpg");
> ...
> };
> and then
>
> center_32_BTN.onPress = function(){
> _root.Ntiles++;
> tile= 'tile'+_root.Ntiles+'_mc';
> _root.center_32_MC.duplicateMovieClip(tile,_root.getNextHighestDepth(),{_x:50,_y:250});}


if i press "center_32_BTN" first of all it will make the copy of the blankmc
(with the image not loaded yet)
if i press "button_btn" on second place it will load it on the first pic
butnot in the duplicated mc.


if i press "button_btn" on first it will load it on the first
pic,obviously...
but if i press now ."center_32_BTN" it wont make any copies..

CheerS!
