How do you bring a value with a RemoteEvent?

So I'm trying to bring a value using a RemoteEvent with FE on So I was thinking "()" might be the value carry but it won't work as it prints "iRexBot"

Here is the script:

Localscript:

local Players = game:GetService('Players')
local Player = Players.LocalPlayer
local Storage=game:GetService('ReplicatedStorage')
local Event=Storage:WaitForChild('ParticalEvent')


function onClick()
    local num = 1
    Event:FireServer(num)
end

script.Parent.MouseButton1Click:Connect(onClick)

Script:

local Storage = game:GetService('ReplicatedStorage')
local Event = Storage:WaitForChild('ParticalEvent')

--Core

function onFired(num)
    print(num)
end
Event.OnServerEvent:Connect(onFired)
