easy problem

[Derpy]

hello im trying practice to know how triggerClientEvent/triggerServerEvent work but need help

server

function sendPlayerCount() 
local playerCount = getPlayerCount() 
triggerClientEvent("onPlayerCountChange",resourceRoot,playerCount) 
end 
addEventHandler("onPlayerJoin",root,sendPlayerCount) 
addEventHandler("onPlayerQuit",root,sendPlayerCount) 

client

addEvent("onPlayerCountChange",true) 
players = 0 
local screenWidth,screenHeight = guiGetScreenSize() 
function drawCount() 
dxDrawText(players,screenWidth/2,screenHeight/2,screenWidth/2,screenHeight/2,tocolor(0,0,255,255),1,"bankgothic") 
end 
addEventHandler("onClientRender",root,drawCount) 
  
function totalFreeroamPlayerNumber(playerCount)  
if playerCount then 
players = playerCount 
else return end 
end 
addEventHandler("onPlayerCountChange",root,totalFreeroamPlayerNumber)

addEvent("onPlayerCountChange", true)
