Script returns nil

Help and Feedback Scripting Support

When I try to return a value from :FireClient, it would give the number to the server, But when it does it sees it as nil.
I tried debugging some things, Somehow the client doesn’t see the number as nil.

– Local Script

game:GetService("ReplicatedStorage").returnClientValue.OnClientEvent:Connect(function()
	local gui = game.Players.LocalPlayer.PlayerGui.ScreenGui
	
	local num = tonumber(gui:WaitForChild("count").count.Value)
	
	warn("real"..num)
	return num

end)

– ServerScript

local playerworld = game:GetService("Workspace")
local plr = game:GetService("Players")
local cubesfolder = playerworld:FindFirstChild("Cubes")
local rep = game:GetService("ReplicatedStorage")
local zab = require(game:GetService("ReplicatedStorage").Services.Zone)
local light = true

plr.PlayerAdded:Connect(function(player)
	local playerValues = player:WaitForChild("savedCubes")

	for _, v in pairs(cubesfolder:GetChildren()) do
		if v:IsA("BasePart") then
			local container = v
			local zone = zab.new(container)
			zone:setDetection("WholeBody")
			zone:setAccuracy("Precise")

			zone.playerEntered:Connect(function(plr)
				if light then
					rep.returnClientValue:FireClient(plr)
					local boolvalue = playerValues:FindFirstChild(v.Name)
					boolvalue.Value = true
					
					warn(rep.returnClientValue:FireClient(plr))
					
					local add = rep.returnClientValue:FireClient(plr) + 1
					
					rep:FindFirstChild("requestDestroy"):FireClient(plr,v)
					rep:FindFirstChild("updateCounter"):FindFirstChild(plr,add)
					zone:destroy()
					rep.sendMessage:FireAllClients(v,plr)
					light = false
					task.wait(0.2)
					light = true
				
				end
			end)
			
		end
	end
end)

You’re using a remote event, of course that’s why it won’t work. Remote events are one-way-communication tools. You’re going to replace it with RemoteFunctions.
