Message not shown

Hi,
I have the following script in fla, but it shows only a blank page without the message, any idea ?

lvReceive.onLoad = function(success:Boolean) {
if (success) {
if(this.result == “emailExists”){
alert(“This email address already exists in the database. Please choose another”);

function alert(message:String):Void{
getURL(“javascript:alert(’”+message+"’);");
