Why won't this ball make chat?

This script is supposed to make a ball chat when you touch it, using the help of a BillboardGui:

debounce = false
ball = script.Parent
dbwait = 5
script.Parent.Touched:connect(function(hit)
	local chat = math.random(1,5)
	if debounce then return end
	--FIRST CHAT OUTCOME--
	
	
	if chat == 1 then
		local ChatBox = Instance.new("BillboardGui")
		ChatBox.Parent = ball
		ChatBox.AlwaysOnTop = true
		local Text = Instance.new("TextLabel",ChatBox)
		Text.Name = "Chat"
		Text.BackgroundTransparency = 1
		Text.BorderSizePixel = 0
		Text.Text = "u r touch me why?"
		Text.FontSize = "Size36"
		Text.TextColor3 = Color3.new(255,255,255)
		debounce = true
		wait(dbwait) -- Debounce end
		debounce = false
		ChatBox:Destroy()
	--SECOND CHAT OUTCOME--
	
	
	elseif chat == 2 then
		if hit.Parent:FindFirstChild("Humanoid")~=nil then
		local ChatBox = Instance.new("BillboardGui")
		ChatBox.Parent = ball
		ChatBox.AlwaysOnTop = true
		local Text = Instance.new("TextLabel",ChatBox)
		Text.Name = "Chat"
		Text.BackgroundTransparency = 1
		Text.BorderSizePixel = 0
		Text.Text = "Hey, "..hit.Parent.Name..", when did I suddenly start using grammar?"
		Text.FontSize = "Size36"
		Text.TextColor3 = Color3.new(255,255,255)
		debounce = true -- Activates the wait time debounce
		wait(dbwait) -- When debounce ends (in seconds)
		debounce = false
		ChatBox:Destroy()
		--THIRD CHAT OUTCOME--
		
		
		elseif chat == 3 then
		if hit.Parent:FindFirstChild("Humanoid")~=nil then
		local ChatBox = Instance.new("BillboardGui")
		ChatBox.Parent = ball
		ChatBox.AlwaysOnTop = true
		local Text = Instance.new("TextLabel",ChatBox)
		Text.Name = "Chat"
		Text.BackgroundTransparency = 1
		Text.BorderSizePixel = 0
		Text.Text = "no grammar party lets rock"
		Text.FontSize = "Size36"
		Text.TextColor3 = Color3.new(255,255,255)
		debounce = true -- Activates the wait time debounce
		wait(dbwait) -- When debounce ends (in seconds)
		debounce = false
		ChatBox:Destroy()
		--FOURTH CHAT OUTCOME--
		
		
		elseif chat == 4 then
		if hit.Parent:FindFirstChild("Humanoid")~=nil then
		local ChatBox = Instance.new("BillboardGui")
		ChatBox.Parent = ball
		ChatBox.AlwaysOnTop = true
		local Text = Instance.new("TextLabel",ChatBox)
		Text.Name = "Chat"
		Text.BackgroundTransparency = 1
		Text.BorderSizePixel = 0
		Text.Text = "enjoi ur fire "..hit.Parent.Name.." okai"
		local fire = Instance.new("Fire",hit.Parent.Torso)
		Text.FontSize = "Size36"
		Text.TextColor3 = Color3.new(255,255,255)
		debounce = true -- Activates the wait time debounce
		wait(dbwait) -- When debounce ends (in seconds)
		debounce = false
		ChatBox:Destroy()
		--FIFTH CHAT OUTCOME--
		
		
		elseif chat == 5 then
		if hit.Parent:FindFirstChild("Humanoid")~=nil then
		local ChatBox = Instance.new("BillboardGui")
		ChatBox.Parent = ball
		ChatBox.AlwaysOnTop = true
		local Text = Instance.new("TextLabel",ChatBox)
		Text.Name = "Chat"
		Text.BackgroundTransparency = 1
		Text.BorderSizePixel = 0
		Text.Text = "enjoi ur smoke just kidding aahahhahahahahahahaahha"
		Text.FontSize = "Size36"
		Text.TextColor3 = Color3.new(255,255,255)
		debounce = true -- Activates the wait time debounce
		wait(dbwait) -- When debounce ends (in seconds)
		debounce = false
		ChatBox:Destroy()
		
		end
		end
		end
		end
		
	end
end)

Everything went well, the billboard is made, and the text, and they were both put in the ball. The problem is no chat appears. While I was testing on studio, I looked inside the ball's children, and the billboard and text were there, but it still didn't appear. So, why won't it appear?
