on the sv/kontakt.php page, the action of the form is to post to the kontakt-fel.php page
<form class="Egen_Kontakt1spalt" id="Skickameddelande_Egen_Kontakt1spalt" name="Skickameddelande_Egen_Kontakt1spalt" method="post" action="kontakt-fel.php">
the UE instance on that page connects to the webassist/email/waue_kontakt-fel_1.phppage
include("../webassist/email/waue_kontakt-fel_1.php");
and the template used by that page is the Blank_16.php
$MailBody = $MailBody . (GetFromPage("templates/Blank_16.php"));
Remeber that all form processing must happen on the forms action page.
if you wish the form on the kontakt.php page to use the UE instance that is on that page, you must change the forms action to do so.
