Gamemode just doen't work at all

[.Winnfield.]

I mean, I looked at this tutorial
[media]http://www.youtube.com/watch?v=D-dvHFIyL5o[/media]
And its sequal, and everything I did was correct, or so it seems, but when I start up a server with the gamemode it just switches to sandbox mode, and it wont let me swtich it back, heres my files

shared.lua

GM.Name 	= "Testmod"
GM.Author 	= "N/A"
GM.Email 	= "N/A"
GM.Website 	= "N/A"

--This is a test of a gamemode
DeriveGamemode( "sandbox" )

function GM:Initialize()

	self.BaseClass.Initialize( self )
	
end

init.lua

AddCSLuaFile( "cl_init.lua" )
AddCSLuaFile( "shared.lua" )

include( 'shared.lua' )


// Serverside only stuff goes here

/*---------------------------------------------------------
   Name: gamemode:PlayerLoadout( ply )
   Desc: Give the player the default spawning weapons/ammo
---------------------------------------------------------*/
function GM:PlayerSpawn( ply )
	self.BaseClass:PlayerSpawn( ply )
	ply:SetGravity( 0,90 )	
	ply:MaxHealth( 125, true )
	ply:SetWalkSpeed( 325 )
		ply:SetRunSpeed( 525 )
end	

function GM:PlayerLoadout( ply )

	ply:StripWeapons()
	ply:Give( "weapon_crowbar" )
	ply:Give( "weapon_pistol" )
end

function GM:PlayerInitialSpawn( ply )
	self.BaseClass:PlayerInitialSpawn( ply )
	if ply:IsAdmin () then
		ply:PrintMessage( HUD_PRINTTALK, "Testmod: Why hello thar!" )
	end
end	
	

cl_init.lua

include( 'shared.lua' )


// Clientside only stuff goes here

Where did I go wrong?

Any errors?

[.Winnfield.]

Yeah, it just starts up in sandbox and won't do anything, I'm trying to make it so you have nothing but a pistol and a crowbar, but I start off with all normal weapons in sandbox, and I don't know how to check for errors.

Did you remember to start your gamemode and not sandbox?

[.Winnfield.]

Yes, I select my gamemode but it just reverts to sandbox, I also tried sv_gamemode but it wont let me change it.

Whats the folder name? If it has a space in it, it wont work.

[.Winnfield.]

It did, let me test to see if it works now.
Alright It loaded now, but I got this error

ERROR: GAMEMODE:'PlayerSpawn' Failed: GamemodeTest/gamemode/init.lua:17: attempt to call method 'MaxHealth' (a nil value)

Also how would I make it so they have more ammo than just 18 shots?

Also again, is there any code that will let me enable serverside fog?

[*Fish*]

on line 17 of init.lua replace
[lua]
ply:MaxHealth( 125, true )
[/lua]

with

[lua]
ply:SetMaxHealth( 125, true )
[/lua]

Sorry that was my alt, it used to work, and I just added some code to allow me to change the player model, but now I'm getting this error in console.
