Several mc post data

regKnop.onRelease = function() {
    naam = naamMc.user.text;
    email = emailMc.email.text;
    wachtwoord = wachtwoord.text;
    //loadVariables("insert.php", "this", "POST");
    var myLV = new LoadVars();
    myLV.onLoad = function(success) {
        if (success) {
            trace("jeuh");
        } else {
            trace("hmz");
        }
    };
    myLV.load("insert.php", "this", "POST");
};

this code posts al nicely into my db, but the trace aint working (I want it to jump to another frame later).
Anyone see what Im doing wrong ?
