How to fix this warning message in my dx script?

[Turbe$Z]

local screenW, screenH = guiGetScreenSize()

addEventHandler("onClientRender", root,
    function()
        dxDrawRectangle(screenW * 0.0021, screenH * 0.7356, screenW * 0.2104, screenH * 0.0367, tocolor(0, 0, 0, 164), false)
        dxDrawText(text, screenW * 0.0014, screenH * 0.7367, screenW * 0.2125, screenH * 0.7722, tocolor(255, 255, 255, 255), 1.00, "default-bold", "center", "center", false, false, false, true, false)
    end
)

addEventHandler("onClientPlayerJoin", root, function()
  local l_2_0 = getPlayerName(source)
  text = "#00ff00" .. l_2_0 .. " csatlakozott!"
  pic = "j"
end
)
addEventHandler("onClientPlayerQuit", root, function(l_3_0)
  local l_3_1 = getPlayerName(source)
  text = "#FF0000" .. l_3_1 .. " lelépett!"
  pic = "q"
end
)

addEventHandler("onClientPlayerChangeNick", root, function(l_4_0, l_4_1)
  text = "" .. l_4_0 .. "#00FF00 Új neve #00BAFF: " .. l_4_1 .. ""
  pic = "c"
end
)


fileDelete("client.lua")

Place onClientRender under onClientPlayerChangeNick event

The variable "text" does not exist as global so in order to access it as a global variable you must define it globally. To make the variable available for access inside this lua file only then all you need to do is simply define it at top. Put this in line 2.

local text = "" -- Global within lua file only which means you can now access it via any function within lua file which has this defined.

If you want to make it accessible all client lua files then define it like this

text = "" -- Global to all client lua files within resource.

Now, it is fully global and available for all client files.
