Why this code keeps error and in the dev console it says : a nil value? [Answered]

Im trying to make a minigame that only have 1 map for now and its speed run. The problem is it keeps saying a nil value until I have no idea. So I need a help here. Here is the dev console : [I use a link because I can't put my screenshot here by using trello] https://trello.com/c/owZ7gkSZ/27-a-nil-value-problem-screenshot

And the script :

--start
local Player1 = game.Players.PlayerAdded:wait()

--variables

NotificationBoard = game.Workspace.StatusBar.Text
TpEnabled = false

enabled = true
Reciver = game.Workspace.Spawn.Spawn1
--Main Tp Script
game.Workspace.TpSender.Touched:connect(function(part)
local hum = part.Parent:FindFirstChild("Humanoid")
    if hum~=nil then 
        if TpEnabled == true then
        if enabled == true then 
            enabled = false
            local t = part.Parent:FindFirstChild("Torso")
            local t2 = Reciver
            t.CFrame = CFrame.new(t2.Position.x, t2.Position.y+4, t2.Position.z)
            Spawn1o = Spawn1o +1
            wait(1)
            enabled = true
            if Spawn1o == 4 then
                Reciver = game.Workspace.Spawn.Spawn2
                if Spawn2o == 4 then

                        Reciver = game.Workspace.Spawn.Spawn5
                            if Spawn5o == 4 then
