Physics.OverlapSphere to get 5 Nearest objects

Ok, So I'm making a Space RPG like game, and I'm having a bit of trouble with the targeting systems. I want the 5 nearest objects within a certain distance to be selected to be targeted. Here is my code for this, but it doesn't work. What am I doing wrong?

//VARIABLES

var targets = new Array();

var selected = Physics.OverlapSphere (transform.position, 500);

var i : int = 0;

function Update () {

   for(var n = 0; n < selected.length; n++) {

          if(selected[n].gameObject.name == "Enemy"){

                  targets[i] = selected[n];
                  i++;
          }

   }

for(var p = 0; p < 2; p++) {

        ///Target[#] Events go here
        

}

}
