Well, the misc.php code creates the template, registers some standard variables to it, then renders it, but if you're trying to use other variables then you need to deal with that. You could try using {vb:raw GLOBALS.HTML}, but if that doesn't work you could use vB_Template:reRegister() where $HTML is created, like:

PHP Code:

$HTML = "test";
vB_Template::preRegsiter('my_template', array('HTML' => $HTML));
