passing the form info via url

if i used the

<?php
$title = $_GET['title'];
echo $title;
?>

function on the 1 st page after the preview why cant i pass this again to the following page ? if i create a form ( non gravity ) it works fine so do i have to add something ?
i tried to just use the same code from the 1 st preview page because we defined the values in the form and it should work ? but it dose not pass to 2nd page... ideas?

I guess we are working with

? i put the stuff there
