How do I find the source of this touch event, location error?

Ive been trying to get a GUI to pop up whenever I enter an invisible block, using the Touch Event.

Heres the code:

touched = false
script.Parent.Touched:connect(function(hit)
    if touched == false then
        touched = true
        if hit.Parent:findFirstChild("Humanoid") ~= nil then
            local char1 = hit.Parent
            player1 = game.Players:GetPlayerFromCharacter(char1)
        end
        --local TB = player1.PlayerGui.TalkButton
        if player1.PlayerGui:findFirstChild("TalkButton") then
            player1.PlayerGui.TalkButton.Grouper.Activator.Value = "Rabbit"
            player1.PlayerGui.TalkButton.Grouper.Visible = true
        end
    end
end)

script.Parent.TouchEnded:connect(function(hit)
    --[[char2 = hit.Parent
    player2 = game.Players:GetPlayerFromCharacter(char2)]]
    if hit.Parent:findFirstChild("Humanoid") then
        local char1 = hit.Parent
        player1 = game.Players:GetPlayerFromCharacter(char1)
    end
    --local TB = player1.PlayerGui.TalkButton
    touched = false
    if player1.PlayerGui:findFirstChild("TalkButton") then
        player1.PlayerGui.TalkButton.Grouper.Visible = false
    end
end)

Before I put the checks for Humanoid, I was getting an error, "Talkbutton is not located in PlayerGui". However, I place that Element inside the Startergui in studio, and when I check inside the player while in solo mode, its in PlayerGui. After I put the checks, the error stopped showing, but now it still wont change the visibility of the gui. Note, my script works perfectly fine in studio, and there were no errors with the TalkButton, but whenever I play the game from the website I've been receiving these problems.

The code is inside a Server Script that is inside the object which I want to touch.

Help, anyone?
