Submit Form Variable To Lightbox

I need to send form variable to a lightbox. What this page suppose to do is user will insert his ID, click Papar ~Display in English, the page will refresh and his examination result will be output in the lightbox. More information on my test page here: [URL] paste 158756873427 into the form and click Papar. That lightbox popup is a remote file so I can paste mysql query in it. Also its not working actually.

I already set the query manually like this:
PHP Code:
$result = mysql_query("SELECT * FROM exam_data WHERE no_KP='158756873427'"); 

What I need is the form from infopendidikan.php to send its variable to the lightbox remote page resultpopup.php. Also you can click on the query popup on the left menu to see the fixed query. resultpopup.php need to retrieve variable from infopendidikan.php.

Anyway this is infopendidikan.php code:
PHP Code:
<?php
//if the "submit"variable does not exist form has not been submitted display initial page
if (!$_POST['submit'])
{ ?> .....
If I can get the result in the lightbox without page refresh that will be more cool. The lightbox I'm using is facebox from [URL].
