Add a Contact Us page to Moodle

I want to add a Contact Us page to Moodle and I used the below code. But this is not working, I get a completely blank page. Can anybody point out the fault of this piece of code? I'm using Moodle 2.5 and I placed this file on the root directory of Moodle. // The number of lines in front of config file determine the // hierarchy of files. require_once(dirname(dirname(__FILE__)).'/../config.php'); $PAGE->set_context(get_system_context()); $PAGE->set_pagelayout('standard'); $PAGE->set_title("Contact US"); $PAGE->set_heading("Contact"); $PAGE->set_url($CFG->wwwroot.'/contact.php'); echo $OUTPUT->header(); // Actual content goes here echo "Hello World"; echo $OUTPUT->footer();
