I noticed this wasn't being associated with a new reply so I added it to the newreply template as follows.
Code:
<form action="newreply.php?do=postreply&t=$threadid" name="vbform" method="post"<if condition="!is_browser('webtv')"> onsubmit="return vB_Editor['$editorid'].prepare_submit(0, $vboptions[postminchars])"</if>>
$adv_editform
Do you see an issue with this code in this template? It's working nicely located here and gives the advanced edit options now every time you invoke the editor.
