Lua problem

I wanna make an if then statement in player.lua to only allow certain classes to be accessed by certain ulx usergroups.

This is what I have:

if t == TEAM_PC and self:IsUserGroup(“silver”) or t == TEAM_PC and self:IsUserGroup(“admin”) or t == TEAM_PC and self:IsUserGroup(“superadmin”) or t == TEAM_PC and self:IsUserGroup(“gold”) or t == TEAM_PC and self:IsUserGroup(“platinum”)
then
Notify(self, 1, 4, “Access Granted”)
end

if t == TEAM_PC and not self:IsUserGroup("silver") then
	Notify(self, 1, 4, "You must be at least a Silver Donator to become this class!")
	return
end

The only problem is that for some reason, When you are one of the allowed user groups, it displays “Access Granted” and then right after displays “You must be at least a Silver Donator to become this class!”
But your job doesn’t change. When I remove:

or t == TEAM_PC and self:IsUserGroup(“admin”) or t == TEAM_PC and self:IsUserGroup(“superadmin”) or t == TEAM_PC and self:IsUserGroup(“gold”) or t == TEAM_PC and self:IsUserGroup(“platinum”)

from my code, It works just fine for only the “silver” usergroup.
