The Script i made its not working for some reason someone please help me?

Server Script

local ReplicatedStorage = game:GetService("ReplicatedStorage") 
local createPartEvent = Instance.new("RemoteEvent", ReplicatedStorage)

local function onCreatePartFired(player,realnow)--The player isn't the player's name it is the player object.
    print(realnow) 
end

createPartEvent.OnServerEvent:Connect(onCreatePartFired)

The server can't access the PlayerGui, so we want to send the MainText.Text with the :FireServer()

Wherever You Do :FireServer() On The createPartEvent

local player = game.Players.LocalPlayer--If you already have player defined in the LocalScript don't do this.
:FireServer(player.PlayerGui.Report.Main.MainText.Text)--Replace :FireServer() with this
