hola que tal gracias por tus respuestas pues el codigo es el mismo que el ejemplo de aqui pero te lo pongo para que lo cheques y no te preocupes por lo de tonto

es solo un decir mio
Código :
on(click){
yourname = _parent._parent.write.yourname.text;
youremail = _parent._parent.write.youremail.text;
yourcomments = _parent._parent.write.yourcomments.text;
if (yourname eq "") {
_parent._parent.write.gb_status.text = "tu nombre carnal";
} else if (youremail eq "") {
_parent._parent.write.gb_status.text = "y el email?";
} else if (!youremail.length || youremail.indexOf("@") == -1 || youremail.indexOf(".") == -1) {
_parent._parent.write.gb_status.text = "y tu email? correrco ";
} else if (yourcomments eq "") {
_parent._parent.write.gb_status.text = "tus comentarios de paro";
} else {
_parent._parent.write.gb_status.text = "cargando datos aguantala";
newEntry = new LoadVars()
newEntry.ref = this
newEntry.submit = "Yes"
newEntry.yourname = yourname
newEntry.youremail = youremail
newEntry.yourcomments = yourcomments
newEntry.sendAndLoad("GuestBook.php?action=write&r="+random(999), newEntry, "POST")
newEntry.onLoad = function(success){
if(success){
_parent._parent.write.gb_status.text = this.gb_status;
_parent._parent.read.loadEntries("Default", 10);
_parent._parent.write.yourname.text = "";
_parent._parent.write.youremail.text = "";
_parent._parent.write.yourcomments.text = "";
}
}
