Well, one thing you could do is to do something like in this article:
https://vborg.vbsupport.ru/showthread.php?t=228112 . Then if you were to change the $specialtemplates line like this:
Code:
$specialtemplates = array('userstats');
you should be able to use $vbulletin->userstats in the custom code. But that's a lot of overhead if all you want is those two numbers. You say the page is blank - what is the page for? What else will be on the page when you're done?
