Pointshop - Point Based on ULX usergroup

[Braden1996]

Hello,
I have [URL="http://facepunch.com/showthread.php?t=1286577"]Pointshop[/URL] installed on my server, as well as the latest version of ULX.
I'm new to Lua, but not to programming in general.
Anyway, I'm trying to make my TTT server give different points to different ULX ranks.
Here is what I've done ([URL="http://pastebin.com/CcCH2rU5"]Full sv_player_extension[/URL]):

if PS.Config.PointsOverTime then
		if self:IsUserGroup("superadmin") then
			givepoints = (PS.Config.PointsOverTimeAmount + 15)
		elseif self:IsUserGroup("admin") then
		    givepoints = (PS.Config.PointsOverTimeAmount + 10)
		elseif self:IsUserGroup("donator") then
			givepoints = (PS.Config.PointsOverTimeAmount + 5)
		else
			givepoints = (PS.Config.PointsOverTimeAmount)
		end
		timer.Create('PS_PointsOverTime_' .. self:UniqueID(), PS.Config.PointsOverTimeDelay * 60, 0, function()
			self:PS_GivePoints(givepoints)
			self:PS_Notify("You've been given ", givepoints, " points for playing on the server!")
		end)

For some reason, this seems to be giving the players 'random' points.
For example, I'm a superadmin, and sometimes I get 25, 20, 15 or sometimes just 10.
Anybody got any ideas?

Does anybody know what's going wrong? I've found a similar problem regarding a script I made that outputs the players name and SteamID into the chatbox upon disconnect. (The script would show the usergroups 'colour' using 'ply:IsUserGroup( "superadmin" )'.

I think you miss posting a bit of the code (there is supposed to be 3 ends as default) but i can help you over steam if you still have this issue

Or you could just post the whole code of that lua file
