Permissions change in code

[soundbarrierpro]

As this is not part of the actual vbpowered page mod and is a permissions modification added to it, I figured I should post here.

Right now I have some pages I created and added permissions to. However, they are only permissions which deny guests.

I want to change to this setting only specific user groups Below is the statement I'm using

PHP Code:

if ($show['guest']) 
    { 
        print_no_permission(); 

    } 


How can I reconfigure so that it's only the user groups I want?

Thank you
