Problems whit for loop in Flash player 7

1

Can someone explain to me why this code is not working when I´m authoring in flash layer 7 whit as1.0, but works in flash player 6

  
 legendas = ["histórico", "eventos", "restaurante", "esplanada", "tenda", "igreja dos lóios", "contactos"];
 for (i=1; i<legendas.length; i++) {
  var bt = _root.attachMovie("button", "btn"+i, i);
  bt.label.text = legendas*;
  bt._x = 10+x;
  bt._y = 430+y;
  x += bt._width+5;
 }

thanks
