No problem. Let us know if you have any other questions, or get stumped somewhere. Using the URL field in Advanced Module Manager can sometimes be tricky. Another alternative is to use the "Components" drop down, and mark HWDVideoShare. That will show for all videos, but if that works, you can then also use the PHP code box (bottom one) to add a check for a specific video ID, like so:
<?php $videoId = JRequest::getInt('id');
if ($videoId == 3)
return true;
else
return false;
?>
The code above get's the Videos' ID from Joomla, which is decoded from the URL. You may need to disable SEF URLs temporarily, and make sure the URL has a parameter id, and that it's not videoid or something. Then, with that id, we're checking if it's the id for video 3 (I made that up), and if so, we return true, which tells Advanced Module Manager to show the module.
Hope that helps, and as always, good luck!
Thanks,
