Die by world problem.

[Snorlaxs]

Ok so i created something that gives a amount based on usergroup and stuff. It works fine problem is that if i die to fall damage or a prop (If i had in the gamemode this is made for) it just creates a error and WONT reset the players score as it supposed to do on death.

Error :

[ERROR] addons/exp_beta/lua/autorun/server/exp_stuff_server.lua:22: attempt to call method 'GetUserGroup' (a nil value)
  1. fn - addons/exp_beta/lua/autorun/server/exp_stuff_server.lua:22
   2. unknown - addons/ulib/lua/ulib/shared/hook.lua:183

Code :

 if ( table.HasValue ( _Groups, attacker:GetUserGroup( ) ) ) then
        _GiveScore( attacker ) 
        elseif ( table.HasValue ( _VIPGroups, attacker:GetUserGroup( ) ) || attacker:IsAdmin( ) || attacker:IsSuperAdmin( ) ) then
        _GiveScoreVIP( attacker )
        end

local _VIPGroups = { "VIP", "owner" }
local _Groups = { "user", "member" }

Check if Attacker a valid player before line 22.
