Storing objects into an array

Im trying to store several objects into an array for further manipulation. There are a lot of them so i didnt name them…i tried like this:


var lucke:Array;
var stLuck:Number=0;
var i:Number;

for(i in this.lucke_mc){
    lucke* = this.lucke_mc*;
    stLuck++;
}

If i trace lucke* it returns undefined, but when i trace this.lucke_mc* it returns the object correctly. So why isnt it working??
