Why Is My Local Script Acting Like a Server Script?

A local script I wrote is acting like a server script. I got someone to play the game and when they touched ChatPart1, the GUI's showed for me. Here's the script so someone could help.

local Player = game.Players.LocalPlayer
local ChatPart1 = game.Workspace.ChatPart1
local PlayerGui = Player:WaitForChild("PlayerGui")
local Chatting1 = ChatPart1.Chatting

local DialogueGui = PlayerGui:WaitForChild("DialogueGui")
local Dialogue = DialogueGui:WaitForChild("Dialogue")
local Name = DialogueGui:WaitForChild("Name")

Dialogue.Visible = false
Name.Visible = false

ChatPart1.Touched:Connect(function()
	if Chatting1.Value == false then
		ChatPart1.Color = Color3.fromRGB(255,0,0)
		Chatting1.Value = true
		Dialogue.Visible = true
		Name.Visible = true
		Dialogue.Text = "Wow, you got up here."
		Name.Text = "fundayelover"
		wait(3)
		Dialogue.Text = "Why did you do this obby though?"
		wait(5)
		Dialogue.Text = "It was meaningless to get up here, there is no badge, nothing."
		wait(8)
		Dialogue.Text = "Well, I guess you aren't bad at obbies."
		wait(5)
		Dialogue.Visible = false
		Name.Visible = false
		Chatting1.Value = false
		ChatPart1.Color = Color3.fromRGB(0,255,0)
	end
end)
