Problem with a function within global function

Hi!

I have a global function for loading php data:

_global.MovieClip.prototype.loadPHP = function(Url, Data) {
    var php_result:LoadVars = new LoadVars();
    php_result.onLoad = function(success:Boolean) {
        if (success) {
            // Connection OK
            if (!php_result.error) {
                this.Title.text = "Some info";
                this.gotoAndStop(2);
            } else {
                this.Title.text = "Some info";
                this.gotoAndStop(3);
            }
        } else {
            // Connection Error
        }
    };
    var php_send:LoadVars = new LoadVars();
    php_send.sendAndLoad(Url,php_result,"POST");
};

It works as it should, except I can’t access the Title.text or gotoAndStop from within the onLoad function. I’ve tried without the “this.” aswell. It works fine outside the onLoad function.

Any ideas?
