Touching part not making BillboardGUi show up?

Hey there, I have this script from a video showing me that if you touch a part, a billboard gui will show up. Here's the script:

local terminateArea = game.Workspace.CDC.TerminateArea
local serverstorage = game:GetService("ServerStorage")
local ExecuteTeam = game:GetService("Teams")("Class-D Personnel")

game.Players.PlayerAdded:connect(function(plr)
    plr.CharacterAdded:connect(function(char)
        local copyTerminateText = serverstorage.TerminateGui:Clone()
        copyTerminateText.Parent = char.Head
    end)
end)

terminateArea.Touched:connect(function(hit)
    if hit.Parent:FindFirstChild("Humanoid")then
        local player = game:GetService("Players"):GetPlayerFromCharacter(hit.Parent)
        if hit.Parent:FindFirstChild("Head").TerminateGui.TerminateText.Visible == false then
            if game.Players.GetPlayerFromCharacter(hit.Parent).Team == ExecuteTeam then
            end 
            hit.Parent:FindFirstChild("Head").TerminateGui.TerminateText.Visible = true
        end
    end
end)

There are no errors, but when I touch the part, nothing shows up. Any help will be greatly appreciated.
