Load movie with formatted dynamic text (only displays images)

hi, i made a movie called clases.swf that contains a dynamic text(that contains images), and it works perfect, but when i load it into a main swf called arte.swf, it only displays the images without text.

here is the code of clases.swf

var format = new TextField.StyleSheet();
var path = “estilo.css”;

format.load(path);
format.onLoad = function(loaded) {
if (loaded) {
my_txt.styleSheet = format;
myLoadVar = new LoadVars ();
myLoadVar.load(“clases.php”)
myLoadVar.onLoad = function (success){
if (success == true) {
my_txt.variable = “texto”
my_txt.htmlText=myLoadVar.texto;
}
}
} else {
my_txt.text = “Error loading CSS file!”;
}
};

how do i modify the code to load the dynamic text on the new invisible movie on arte.swf (on the main swf)???

please i need help urgently!!!
