Bad argument @ 'addEventHandler' [Expected function at argument 3, got nill]

[Tony Brand]

hi, i am newbie in lua,
i want to make a radio system that plays sound from vehicle for all players
so i downloaded radio :O system from here
but it doesn't have server side, so i made it
my problem is that i get error when running resource but i think i don't have any mitake...
error is Bad argument radio/server.lua:2 @ 'addEventHandler' [Expected function at argument 3, got nill]
& radio/server.lua:10@ 'addEventHandler' [Expected function at argument 3, got nill]

whole the server side is this:
 

addEvent("getSoundStopForAll", true)
addEventHandler("getSoundStopForAll", root, getSoundStopForAll )
	function getSoundStopForAll( )
		stopSound(Stream[source])
		Stream[source] = nil
		sPath[source] = nil
	end

addEvent("sendSoundForAll", true)
addEventHandler("sendSoundForAll", root, sendSoundForAll )
	function sendSoundForAll( )
		triggerClientEvent(root, "syncradio",  sendSoundForAll)
	end

also here is syncradio ClientEvent
 

addEvent("syncradio", true)
addEventHandler("syncradio", root,
	function( )
		local x, y, z = getElementPosition(source)
		Stream[source] = playSound3D(channelTable[channelTable[path]], x, y, z)
		setSoundEffectEnabled ( Stream[source], "compressor", true )
		sPath[source] = path
		setSoundVolume(Stream[source], volume)
		setSoundMaxDistance(Stream[source], 50)
		attachElements(Stream[source], source)
	end)

 

[iMr.WiFi..!]

addEvent("getSoundStopForAll", true)
addEventHandler("getSoundStopForAll", root, 
	function ( )
		stopSound(Stream[source])
		Stream[source] = nil
		sPath[source] = nil
	end
)
addEvent("sendSoundForAll", true)
addEventHandler("sendSoundForAll", root,
	function ( )
		triggerClientEvent(root, "syncradio", root)
	end 
)

errors solved but now there are 4 warnings in debugscript gui and music doesn't play!

the part of that client side that made errors:

addEvent("syncradio", true)
addEventHandler("syncradio", root,
	function( )
		local x, y, z = getElementPosition(source)
		Stream[source] = playSound3D(channelTable[channelTable[path]], x, y, z)
		setSoundEffectEnabled ( Stream[source], "compressor", true )
		sPath[source] = path
		setSoundVolume(Stream[source], volume)
		setSoundMaxDistance(Stream[source], 50)
		attachElements(Stream[source], source)
	end)

Well... source is root, you can't possibly get the position of the root element, has to be an entity,
The other thing is that channelTable[channelTable[path]] evaluates to nil, can't see any of those variables anywhere in your snippet.
