putting some action on an instance of a movie clip

hi, I have a small problem. I made a scene in which 6 movie clips are duplicated and created according the values of an array. In each movie clip there is an button. the problem is that with the way I am trying to do it, the buttons don't work. What I want to do is when you click on each button of each movie clip to go and open the URL that is on the Links_array variable. With the following code, that doesn't work. The code is the one that follows:

var i;
var yposition;
var depth;
var menu;

theMenu="Products,Quality,Technology,Contact,Forums,Search"
theLinks="products.asp,quality.asp,technology.asp,contact.asp,forums.asp,search.asp"
theImages="test.JPG,RiverSumida.JPG,Rhododendron.JPG,test.JPG,RiverSumida.JPG,Rhododendron.JPG"

Menu_array=theMenu.split(",");
Menu_length=Menu_array.length;
Links_array=theLinks.split(",")
Links_length=Links_array.length;
Images_array=theImages.split(",");
Images_length=Images_array.length;


depth=-1;
i=1;
yposition=0;
xposition=300;
Menu._visible=0;

//Dynamic Menu Creation
for(i=0;i<Menu_length;i++){
duplicateMovieClip(Menu,"Menu" add i,depth);
setProperty("Menu" add i,_y,yposition);
setProperty("Menu" add i,_x,xposition);
set("Menu" add i add ".myText",Menu_array[i])
_root["Menu" add i].myImage.mySecondImage.loadMovie(Images_array[i]);
_root["Menu" add i].myLink.onRelease=function(){
getURL(Links_array[i],"_SELF","POST");
}
depth++;
yposition+=80;
}


I would appreciate any answer. Thank you
