Trying to revive sandbox chatsounds, need help with old code

[APNxRPG24]

Chatsounds Errors:

[ERROR] addons/chatsounds/lua/autorun/server/chatsounds.lua:1045: attempt to call global 'ValidEntity' (a nil value)
  1. unknown - addons/chatsounds/lua/autorun/server/chatsounds.lua:1045

Timer Failed! [Simple][@addons/chatsounds/lua/autorun/server/chatsounds.lua (line 1070)]

If I can get help to fix this, I can give out the files if anyone wants this addon.
Since I've looked around for this and I can only find it for DarkRP or just old broken code like this. I remember I almost had it working before many months ago, but I think I just forgot about it or gave up.

I also kind of want to fix the "ravebreak" addon if anyone remembers that.
It's having these errors:

[ERROR] bad argument #1 to '?' (string expected, got no value)
  1. unknown - [C]:-1

Timer Failed! [Simple][@addons/ravebreak/lua/autorun/rave.lua (line 61)]

I would appreciate help, thanks for looking.

We need code.

Replace all instances of ValidEntity with IsValid

[QUOTE=code_gs;47550320]We need code.

Replace all instances of ValidEntity with IsValid[/QUOTE]

That is the only part of code where I found a suggestion, and I tried that exact thing. There is only 1 instance of ValidEntity, and when I replace it with IsValid the addon appears to go away. Meaning when I try to type a chatsound I don't even get errors or anything like the addon doesn't exist.

And here's the lines of code with errors, let me know if you want more (or the whole thing). My mistake.

chatsounds.lua:

1044	local function DoSound( ply, snd, num )
1045		if IsValid(ply) then
1046			if MutedPlayers[ply:UniqueID( )] then return; end
1047			num = num or 0
1048			local pitch = math.random( 94, 102 )
1049			for i = 1, num+1 do
1050				ply:EmitSound(Sound(snd), 90, pitch)
1051			end
1052		end
1053	end
1054
1055	local function PlayerSay( ply, text )
1056		if MutedPlayers[ply:UniqueID( )] then return; end
1057		local TextList = GetList(text)
1058		
1059		if #TextList > 1 then
1060			table.sort(TextList, function(a, b) return a[1] < b[1] end)
1061		end
1062		
1063		local _, num = string.gsub(text, "[!]", "")
1064		local Time = 0
1065		for k,v in pairs(TextList) do
1066			local sound = SoundList[v[2]][math.random(#SoundList[v[2]])]
1067			if not sound then return; end
1068			if sound[2] and sound[2] ~= "" then
1069				local i
1070				timer.Simple(Time, DoSound, ply, sound[2], num)
1071			end
1072			Time = Time + sound[1]
1073		end
1074	end

rave.lua:

1  	if SERVER then
2  		AddCSLuaFile("autorun/rave.lua")
3  		
4  		function InitRave()
5  			resource.AddFile("sound/ravebreak.mp3")
6  		end
7  		hook.Add("Initialize", "RaveInit", InitRave)
8  
9  		function RaveBreakSay( pl, text, teamonly )
10 			if (text == "!ravebreak") then
11 				pl:ConCommand("ravebreak_now")
12 				return text
13 			end
14 		end
15 		hook.Add("PlayerSay", "RaveBreakSay", RaveBreakSay)
16 
17 		function RaveCommand( pl, cmd, args )
18 			if pl:IsAdmin() then
19 				if not Raving then
20 					RaveBreak()
21 				else
22 					pl:ChatPrint("You're already raving dude!")
23 				end
24 			end
25 		end
26 		concommand.Add("ravebreak_now",RaveCommand) 
27 		
28 		function RaveBreak()
29 			umsg.Start("RaveBreak")
30 			umsg.End()
31 
32 			Raving = true
33 			
34 			// 1 second buildup
35 			timer.Simple(1,function()
36 				hook.Add("Think","RaveThink",RaveThink)
37 			end)
38 			
39 			timer.Simple(24,function()
40 				hook.Remove("Think","RaveThink")
41 				umsg.Start("RaveEnd")
42 				umsg.End()
43 				Raving = false
44 			end)
45 			
46 		end
47 
48 		function RaveThink()
49 			for k, v in pairs(player.GetAll()) do
50 				v:PrintMessage(HUD_PRINTCENTER,"RAVE BREAK!")
51 			end
52 		end
53 
54 	else
55 
56 		RAVESOUND = "ravebreak.mp3"
57 
58 		function RaveBreak(um)
59 			RunConsoleCommand("stopsounds")
60 
61 			timer.Simple(0.01,surface.PlaySound,RAVESOUND)
62 			timer.Simple(1,function()
63 				hook.Add("RenderScreenspaceEffects", "RaveDraw",RaveDraw)
64 			end)
65 		end

Hey thanks, I have seen that before but didn't really try because I don't know the slightest thing about Lua/coding.
However, I was able to fix chatsounds. Except sometimes when I type the word, it will be won't active until I do another word. This seemed to be common on the "Hello!" sound.

Also I was not able to fix ravebreak since I'm not even sure what that first error means. I didn't know how to fix the timer either because it was different than that chatsounds one. Do you think you would know anything about those errors?
