Cloned GUI Won't Destroy On First Click? Debounce Problems?

I've got some long code here, but I'll go ahead and give you guys the most important pieces in green.

--This is what happens first when the player steps on the brick.
d=true
script.Parent.Touched:connect(function(hit)
    if d and hit.Parent:FindFirstChild("Humanoid") and script.Parent.BrickColor~=BrickColor.Green() then
        d=false
        local plr=game.Players:FindFirstChild(hit.Parent.Name)
        hit.Parent.Humanoid.WalkSpeed=0
plr.Character.JumpDisabled.Disabled=false
        script.Parent.BrickColor=BrickColor.Green()
        plr.Court.Value=script.Parent.Parent.Name
        plr.team.Value = "Home"
        hit.Parent.Torso.CFrame=CFrame.new(script.Parent.t.Position)
        script.Parent.Parent.gotnext.Value=script.Parent.Parent.gotnext.Value+1
        plr.PlayerGui.scoreboard:findFirstChild(script.Parent.Parent.Name).Visible=true
        plr.TeamColor=BrickColor.new("Mid gray")
        script.Parent.Sound:Play()
wait(1.33)
script.Parent.Sound:Stop()  
        d=true
    end
end)

--This is a GUI that makes them be removed from the Brick.
local part=game.Workspace.Part1 -- the part you want to teleport the player to teleport to
local d=true -- debounce
local plr = game:GetService("Players"):FindFirstChild("Humanoid")
script.Parent.Touched:connect(function(limb)
    if limb.Parent:FindFirstChild("Humanoid") then
    d=false
    local RepStorage = game:GetService("ReplicatedStorage")
    local plr=game:GetService("Players"):FindFirstChild(limb.Parent.Name)
    local playerGui = plr:WaitForChild('PlayerGui') 
    local ExitCourt = RepStorage.ExitCourt
    local EC = ExitCourt:Clone() --Cloned GUI
    EC.Parent = playerGui
    EC.TextButton.Visible = true
    local button = EC.TextButton
    d=true
button.MouseButton1Down:connect(function()
        plr.Character.Torso.CFrame=part.CFrame+Vector3.new(0,2,0)
        EC:Destroy() --Won't destroy on first click (Link down below)
        script.Parent.Parent.gotnext.Value = script.Parent.Parent.gotnext.Value - 1
        plr.PlayerGui.scoreboard:findFirstChild(script.Parent.Parent.Name).Visible=false
        script.Parent.BrickColor=BrickColor.Blue()
        plr.Team = game.Teams["No Team"]
        limb.Parent.Humanoid.WalkSpeed=16
        plr.team.Value = ""
        plr.Court.Value=game.Workspace.nocourt.Name
        plr.Character.JumpDisabled.Disabled=true
    end)
elseif plr.Court.Value==game.Workspace.nocourt then --Just a different value, still works.
    if d==true then
        d=false
        local RepStorage = game:GetService("ReplicatedStorage")
    local plr=game:GetService("Players"):FindFirstChild(limb.Parent.Name)
    local playerGui = plr:WaitForChild('PlayerGui') 
    local ExitCourt = RepStorage.ExitCourt
    local EC = ExitCourt:Clone() --Cloned GUI
    EC.Parent = playerGui
    EC.TextButton.Visible = true
    local button = EC.TextButton
button.MouseButton1Down:connect(function()
        plr.Character.Torso.CFrame=part.CFrame+Vector3.new(0,2,0)
        EC:Destroy() --Won't destroy on first click (Link down below)
        script.Parent.Parent.gotnext.Value = script.Parent.Parent.gotnext.Value - 1
        plr.PlayerGui.scoreboard:findFirstChild(script.Parent.Parent.Name).Visible=false
        script.Parent.BrickColor=BrickColor.Blue()
        plr.Team = game.Teams["No Team"]
        limb.Parent.Humanoid.WalkSpeed=16
        plr.team.Value = ""
        plr.Court.Value=game.Workspace.nocourt.Name
        plr.Character.JumpDisabled.Disabled=true
        d=true
    end)
        end
    else
        return
    end
end)
