Variable help

gold = 1000

function GM:HUDPaint()
	self.BaseClass:HUDPaint()
	local ply = LocalPlayer()
	local gold = LocalPlayer():gold()
	
	surface.CreateFont( "ScoreboardText", 40, 250, true, false, "goldfont" )
	surface.SetTextColor( 255, 255, 255, 255)
	surface.SetTextPos( 36, 15 )
	surface.SetFont( "goldfont" )
	surface.DrawText( "$", gold )
end

in-game, it constantly complains that the variable gold does not exist. but it DOES as you can see 'gold = 1000' that's how a variable is defined right? How could I display a custom variable on a HUD (meaning NOT health or ammo) without errors?
Thanks.

EDIT: one more question, if I put the variable in shared.lua, when it is modified serverside it will update the client right? How could I make it be a 'shared' variable, or will it be one?
EDIT2: Full Error

[ERROR] gamemodes/casino/gamemode/cl_init.lua:15: attempt to call method 'gold' (a nil value)

You redefined gold as local gold = LocalPlayer():gold(). (line 6 in your code)
Remove that line. LocalPlayer():gold() isn't anything.

EDIT: Shared variables won't update for the client when you update them on the server.
You need to send the client the variable with the [URL=http://gmodwiki.net/Lua/Libraries/net]net[/URL], [URL=http://gmodwiki.net/Lua/Libraries/umsg]umsg[/URL]/[URL=http://gmodwiki.net/Lua/Libraries/usermessage]usermessage[/URL], and (in the case of client-server) [URL=http://gmodwiki.net/Lua/Libraries/concommand]concommand[/URL] libraries.

You're trying to define gold as a player function, make a MetaTable for that.

Thanks, but is there a solution to display custom variables on the HUD? I know it fixes when I remove that line but what is the right way to do it?

The way you are trying to do it is the correct way.
You just had that line which was botching everything up.
To make a HUD display custom variables, just use a variable for what the HUD displays and change that variable whenever you want. Changing the variable will change the HUD in real time.

For example, the following script will add 1 pwn per second to your HUD. Try running it to see what I mean.
[lua]
local pwn = 0
hook.Add("HUDPaint", "Pwn", function()
draw.SimpleText(pwn, "HUDNumber1", 50, 50, Color(100,100,100))
end)

function AddPwn()
pwn = pwn+1
timer.Simple(1, AddPwn)
end
timer.Simple(1, AddPwn)
[/lua]

Also, your surface.DrawText() is done weird.
If you want to stick two pieces of text together, don't add a comma, add two dots. (..)

[lua]
print("haha".." You're ".." Fu".."nny"..".")
--This would print
--haha You're Funny.
--into the console.
[/lua]

And lastly, surface.SetColor(255,255,255,255) should be surface.SetColor(Color(255,255,255,255))
