Clientside Script not executing?

[Dooskington]

I have these scripts:

cl_init.lua
cl_mainmenu.lua
init.lua
shared.lua
player.lua

cl_init and cl_mainmenu are both clientside, and I want to have this code inside cl_mainmenu:

function mainMenu()

local mainMenu = vgui.Create( "DFrame" )
mainMenu:SetSize( 620,  710 )
mainMenu:SetTitle( "Herb Roleplaying" )
mainMenu:SetVisible( true )
mainMenu:SetDraggable( false )
mainMenu:ShowCloseButton ( false )
mainMenu:MakePopup()
mainMenu:Center()

local PropertySheet = vgui.Create( "DPropertySheet" )
PropertySheet:SetParent( mainMenu )
PropertySheet:SetSize( 600, 640 )
PropertySheet:Center()

	-- Character Sheet

local CharacterSheetBox = vgui.Create( "DPanel" , PropertySheet)
CharacterSheetBox:SetPos( 25, 50 )
CharacterSheetBox:SetSize( 50,  50 )
CharacterSheetBox.Paint = function() -- Paint function
    surface.SetDrawColor( 50, 50, 50, 255 ) -- Set our rect color below us; we do this so you can see items added to this panel
    surface.DrawRect( 0, 0, CharacterSheetBox:GetWide(), CharacterSheetBox:GetTall() ) -- Draw the rect
end

		-- Character Name

		local CharacterNameBox = vgui.Create( "DPanel" , CharacterSheetBox)
		CharacterNameBox:SetPos( 10, 10 )
		CharacterNameBox:SetSize( 570,  30 )
		CharacterNameBox.Paint = function() -- Paint function
			surface.SetDrawColor( 70, 70, 70, 255 ) -- Set our rect color below us; we do this so you can see items added to this panel
			surface.DrawRect( 0, 0, CharacterNameBox:GetWide(), CharacterNameBox:GetTall() ) -- Draw the rect
		end

			local CharacterNameLabel = vgui.Create( "Label", CharacterNameBox )
			CharacterNameLabel:SetPos( 7, 8 )
			CharacterNameLabel:SetText( "Character Name:" )
			CharacterNameLabel:SizeToContents()


			local CharacterName = vgui.Create( "DTextEntry", CharacterNameBox )
			CharacterName:SetPos( 120, 5 )
			CharacterName:SetTall( 20 )
			CharacterName:SetWide( 360 )
			CharacterName:SetEnterAllowed( true )
			
			local CharacterNameChange = vgui.Create( "DButton", CharacterNameBox)
			CharacterNameChange:SetText( "Change" )
			CharacterNameChange:SetPos( 500, 5 )
			CharacterNameChange:SetSize( 50,20 )
			CharacterNameChange.DoClick = function()
				RunConsoleCommand( "kill" )
			end
		 
		-- Character Details

		local CharacterDetailBox = vgui.Create( "DPanel" , CharacterSheetBox)
		CharacterDetailBox:SetPos( 10, 45 )
		CharacterDetailBox:SetSize( 570,  30 )
		CharacterDetailBox.Paint = function() -- Paint function
			surface.SetDrawColor( 70, 70, 70, 255 ) -- Set our rect color below us; we do this so you can see items added to this panel
			surface.DrawRect( 0, 0, CharacterDetailBox:GetWide(), CharacterDetailBox:GetTall() ) -- Draw the rect
		end

			local CharacterDetailLabel = vgui.Create( "Label", CharacterDetailBox )
			CharacterDetailLabel:SetPos( 7, 8 )
			CharacterDetailLabel:SetText( "Character Details:" )
			CharacterDetailLabel:SizeToContents()

			local CharacterDetail = vgui.Create( "DTextEntry", CharacterDetailBox )
			CharacterDetail:SetPos( 120, 5 )
			CharacterDetail:SetTall( 20 )
			CharacterDetail:SetWide( 360 )
			CharacterDetail:SetEnterAllowed( true )

			local CharacterDetailChange = vgui.Create( "DButton", CharacterDetailBox)
			CharacterDetailChange:SetText( "Change" )
			CharacterDetailChange:SetPos( 500, 5 )
			CharacterDetailChange:SetSize( 50,20 )
			CharacterDetailChange.DoClick = function()
				RunConsoleCommand( "kill" )
			end
			
		-- Employment
		
			local JobsCategory = vgui.Create( "DCollapsibleCategory", CharacterSheetBox )
			JobsCategory:SetPos( 10, 80 )
			JobsCategory:SetSize( 570,300 )
			JobsCategory:SetExpanded( 1 )
			JobsCategory:SetLabel( "Employment" )
			
				local CitizenBox = vgui.Create( "DPanel" , JobsCategory)
				CitizenBox:SetPos( 10, 30 )
				CitizenBox:SetSize( 50,  50 )
				CitizenBox.Paint = function() -- Paint function
				surface.SetDrawColor( 70, 70, 70, 255 ) -- Set our rect color below us; we do this so you can see items added to this panel
				surface.DrawRect( 0, 0, CitizenBox:GetWide(), CitizenBox:GetTall() ) -- Draw the rect
				end

PropertySheet:AddSheet( "Character", CharacterSheetBox, "gui/silkicons/user", false, false, "All general info on your character." )
PropertySheet:AddSheet( "Server Rules", test, "gui/silkicons/page", false, false, "The rules of the server." )
end
usermessage.Hook("mainMenu", mainMenu)

But for some reason the above code does not work in cl_mainmenu. It is supposed to be activated by

function GM:ShowHelp( ply ) -- This hook is called everytime F1 is pressed.
    umsg.Start( "mainMenu", ply ) -- Sending a message to the client.
    umsg.End()
end --Ends function

in init.lua, but this will not work. It only works if the code is in cl_init. If the code is in cl_mainmenu, it says unhandled exception for mainMenu.

I am pretty sure that I imported everything correctly in init.lua:

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

include('shared.lua')
include('player.lua')

Any help would be appreciated.

Are you including cl_mainmenu in cl_init?

[Freze]

Make sure to put in cl_init:
[lua]include("cl_mainmenu.lua")[/lua]

[Dooskington]

Thanks guys, it worked.

Now could somebody be so kind as to tell me why that needs to be there? from what I gathered, cl_init is the master script for all clientside scripts. Am I correct?

[Tyler B.]

Yes, but you're not telling it to load the mainmenu file.

It's the same as the init file, you have to include each file you want to run.

Okay, thanks again!
