Tweenlite in a movie clip called from variable

i’m trying to run a loop, so a sequence of movie clips, one after the other, should “blink” as a wave.

Tried the code below, without success. nothing happens. What could be wrong?

The movie clips are named “menu1” thru “menu11”.


function ondaMenu  (){
for (var i:Number = 1; i < 12; i++) {
 TweenLite.to ("menu"+i,1,{_alpha:35,ease:Quad.easeOut,delay:1+i/10});

}
}
ondaMenu();
