When you use 'AND', then the expression is true only if the expressions on both sides of AND are true. In this code:

if ($vbulletin->userinfo['usergroupid'] != 6 AND 7)

the left side is $vbulletin->userinfo['usergroupid'] != 6, and the right side is just 7. As it turns out (using php the rules of type conversion), an integer converts to 'false' if it's 0 and true otherwise, so the expression '7' is always true. So the result is the same as this:

PHP Code:

if ($vbulletin->userinfo['usergroupid'] != 6) 


I hope that makes sense.

Or maybe a better way to put it would be that the != has higher precedence than AND, so if you were to put parens in the expression to make it clear, what you'd have is this:

PHP Code:

if (($vbulletin->userinfo['usergroupid'] != 6) AND (7)) 


which is obviously not what you want.
