Problems with duplicateMovieClip and embedded movies

programming flash

Hi All!

I am having an issue creating duplicatemovieclips with dynamic names

Here is my code:

[AS]
function subMenuWork(menu_items, menu_labels, y_value, x_value){
attachMovie(“subMenuMC”, “subInstance”, 40);
subInstance._y = 400;
subInstance._x = x_value;
subInstance._alpha = 0;

n = 1;


while (n <= menu_items){
	nn = eval("sub"+n);
	trace("nn is " + eval(nn));
	duplicateMovieClip(subInstance, nn, 40);
	
	
	if (n == 0){
		sub0._y = y_value + 24;	
	}
	n++;
}

}
[/AS]

Trace say that the variable nn is undefined…

Please help.
