Why is my GUI enabling script returning nothing?

I'm trying to make a simple script to make a GUI enable on touching something but I'm having no luck.

At first, this is what I tried:

script.Parent.Touched:connect(function(HIT)
    local H = HIT.Parent:FindFirstChild("Humanoid")
    if H then
        game.Players.LocalPlayer.PlayerGui.BoatGUI.Enabled = true
    end
end)

It's in a local script in a block, I'm not sure why it didn't work because the same line of code (game.Players.LocalPlayer.PlayerGui.BoatGUI.Enabled = false) works in the GUI to make it become invisible when the player first joins.

Next, I tried something with remotes which also didn't work (probably because I'm bad at remotes).

Here is that:

Local script in the same block:

script.Parent.Touched:connect(function(HIT)
    local H = HIT.Parent:FindFirstChild("Humanoid")
    if H then
        game.StarterGui.BoatGUI.TextButton.Script.RemoteFunction:InvokeServer(H.Parent.Name)
    end
end)

The script is in the Gui in StarterGui with a RemoteFunction in the script:

script.RemoteFunction.OnServerInvoke = function(player)
    game.Players[player].PlayerGui.BoatGUI.Enabled = true
end

If someone could fix this or tell me what I was doing wrong I would appreciate it.
