Did you paste a partial code?

Should have an if here

if(isset($_POST['getringan'])){

and also wrap it with another curly brace at the end

I guess the first thing should do is add this to the top of your script

error_reporting(E_ALL | E_NOTICE);
ini_set('display_errors', '1');

See if there are any errors.

Next can explain how it's not working, what you are not seeing or expecting.
