How do I use vb permissions in an html page?

[nanaimobar]

I've got a html page with an applet inside. I've tried using web templates to retain permissions but can't get the save function of game to work. The applet save function requires reading/storing applet content and then updating html web page and applet the next time a member plays the applet. Html page and applet with save function works fine if placed within a folder on my server. So...

I was wondering:
how would I include vb user group permissions in the html file so that only certain usergroups can access and play game?

You can see puzzle, without save function, here (https://punzhupuzzles.com/forums/view.php?pg=crswrdpuz).

$curdir = getcwd();
chdir('./forums');
require_once('./global.php');
chdir($curdir);

if (!is_member_of($vbulletin->userinfo, X))
{
print_no_permission();
}
Where X is the usergroup ID that is allowed to access the page.

That will only work on a PHP-page. You can not do this in a plain HTML page.
