Show page where form was filled

I have created a site with Chronoforms as a module on multiple pages. (Joomla 1.5, current CF) How or which field would I edit or create to show in the emailed result which url the page was filled out at?

Solved! Just added

<?php 
$ref = getenv("HTTP_REFERER"); 
echo $ref;
?>

at the end of the email template. If you anyone has a better way, let me know. Otherwise, I hope this helps someone else someday.
