Having a problem with derma sliders.

[PETREKILLAH]

I'm trying to make a simple lives counter addon and I've run into a little problem with the OnValueChanged function. Whenever I try to override the function, I get an error that says:
[ERROR] lua/myscript.lua:41: function arguments expected near '='
1. unknown - lua/myscript.lua:0
On the wiki, the function only has one argument so I doubt the amount of arguments is the problem. There is a lack of any examples or further documentation about this which is pretty frustrating. Anyone have an ideas what I'm doing wrong?

local NumSlider = vgui.Create("DNumSlider", Frame)
NumSlider:SetPos( 100,23 )
NumSlider:SetWide( 200 )
NumSlider:SetMax( 1000 )
NumSlider:SetMin( 0 )
NumSlider:SetDecimals(0)
NumSlider:OnValueChanged = function( number )
	net.Start("TicketAmount")
	net.WriteInt( number, 16 )
	net.SendToServer()
end

[QUOTE=Moat;51523609]Your "NumSlider:OnValueChanged = function( number )" should be
[lua]
NumSlider.OnValueChanged = function( self, number )
-- or
function NumSlider:OnValueChanged( number )
[/lua][/QUOTE]

Thank you so much for your quick reply! The second one worked but the first one didn't for some reason. I'll just use this one for now.
