Whats wrong with this script?

function kill()--from here...
    M=Instance.new("Message",workspace)
    M.Text="Deleting BasePlate ..."
    Wait(3)
    M.Text=". . . "
    wait(1)
    M.Text=" . . ."
    wait(1)
    M.Text=". . . "
    wait(1)
    M.Text="Now!"
    wait(1)
    M:remove()
    H=Instance.new("Hint",workspace)
    H.Text ="Troll"
    wait(5)
    workspace.BasePlate:Destroy()
    H.Text ="Trolololololololololololololololololo"
end
game.Players.PlayerAdded:connect(kill)



local screenGui = Instance.new("ScreenGui")
screenGui.Parent = script.Parent
local textButton = Instance.new("TextButton")
textButton.Parent = screenGui
textButton.Position = UDim2.new(0, 10, 0,10)
textButton.Size = UDim2.new(0,350 , 0,200 )
textButton.BackgroundColor3 = BrickColor.White().Color
textButton.Text = "Save your life!"--... to here I know nothing is wrong

tab ={}
Kids=workspace:GetChildren()
table.insert(tab,Kids)
for i,v in pairs(tab) do
    if BasePlate==v then
        textButton.Text="too late to save your life"
    end
end
textButton.MouseButton1Down:connect(function()

if workspace.BasePlate.Position==Vector3.new(0, -0.61, 0) then 
     P=Instance.new("Part",workspace)
    P.Anchored=true
    P.Position =Vector3.new(512, 1.2, 512)
    else M=Instance.new("Message",workspace)
        M.Text="Your life is saved :D"
        wait(3) M:remove()
    end
end)

Everything goes well but When I click nothing happens and the Gui just says click here to save your life Output:19:49:37.754 - Disconnected event because of exception What is my error?
