I got problems while ima making a npc chat system?

this is script i got problems in "RunServices" it says "expected '(' to close')' at line 55

local RunService = game:GetService("RunService") local UIS = game:GetService("UserInputService") local Player = game:GetService("Players")

local DetectedNPC = nil local Detected = false local Chatting = false local Skip = false local Exit = false

local Player = Player.LocalPlayer local Camera = game.Workspace.CurrentCamera

local Gui = script.Parent local Sounds = Gui.Sounds local PromptLabel = Gui.PrompLabel local LineLabel = Gui.LineLabel

local Character = Player.Character or Player.CharacterAdded:Wait() local CharHMR = Character:WaitForChild("HumanoidRootPart")

local NPCS = game.Workspace:WaitForChild("NPC")

UIS.InputBegan:Connect(function(Input) if Input.KeyCode == Enum.KeyCode.X then if Chatting == true then Skip = true Sounds.Click:Play() end end end)

UIS.InputBegan:Connect(function(Input) if Input.KeyCode == Enum.KeyCode.Z then if Chatting == true then Exit = true Sounds.Click:Play() end end end)

UIS.InputBegan:Connect(function(Input) if Input.KeyCode == Enum.KeyCode.E then

	if Detected == true then
		local Lines = DetectedNPC:FindFirstChildren("Lines")
		
		if Line then
			Sounds.Click:Play()
			
			Chatting = true
			Detected = false
			
			LineLabel.Text = " "
			
			PromptLabel:TweenSize(UDim2(0, 0, 0, 0), "Out", "Linear", 0.2)
		    LineLabel:TweenPosition(UDim2(0, 0, 0.8, 0), "In", "Linear", 0.2)
		
		wait (0.5)
		
		for i, Line in pairs(Lines:GetChildren()) do
			local Text = Line.Value
			
			for i = 1, #Text do
				LineLabel.Text = string.sub(Text, 1, i)
				Sounds.Talk:Play()
				if Skip == true then 
					Skip = false
					LineLabel.Text = Text
					break
				end
				if Exit == true then
					break
				end
				wait(0.07)
				end
				if Exit == ture then
					Exit = false
					break
				end
				repeat wait() until Skip == true or Exit == true
				Skip = false
			end
			
			Exit = false
			Skip = false
			
			PromptLabel:TweenSize(UDim2(0, 0, 0, 0), "Out", "Linear")
		    LineLabel:TweenPosition(UDim2(0, 0, 1.2, 0), "In", "Linear")
		
		wait(0.5)
		
		Chatting = false
		Detected = false
		
		end
		end
	end
	
	
end

RunService:RenderStepped:Connect(function()

if Detected == false and Chatting == false then
	for i, NPC in pairs(NPCS:GetChildren()) do
		local Humanoid = NPC:FindFirstChild("Humanoid")
		local HMR = NPC:FindFirstChild("HumanoidRootPart")

		if Humanoid and HMR then
			if (HMR.Position - CharHMR.Position).magnitude < 15 then
				Detected = true
				DetectedNPC = NPC
				PromptLabel:TweenSize(UDim2(0, 60, 0, 60), "In", "Linear")
				print(DetectedNPC.Name) 
				
			end
		end			
	end
end

if Detected == true and Chatting == false then
	local Humanoid = DetectedNPC:FindFirstChild("Humanoid")
	local HMR = DetectedNPC:FindFistChild("HumanoidRootPart")
	
	if Humanoid and HMR then

			Detected = false
			DetectedNPC = nil
				PromptLabel:TweenSize(UDim2(0, 0, 0, 0), "Out", "Linear")
			print("none npc detected you probaly are talking with air :D (someone really read this?)")
		else
				local WTPS = Camera:WorldToScreenPoint(HMR.Position)
				PromptLabel.Position = UDim2.new(0, WTSP.X, 0, WTPS.Y)
	end
end

end)

if Chatting == true then local Humanoid = DetectedNPC:FindFirstChild("Humanoid") local HMR = DetectedNPC:FindFistChild("HumanoidRootPart")

	if Humanoid and HMR then
		Camera.CameraType = Enum.CameraType.Scriptable
		Camera.CFrame = Camera.CFrame:Lerp(HMR.CFrame * CFrame.new(-4, 4, -7 ) * CFrame.fromOrientation(math.rad(-20), math.rad(215), 0) 0.07) 
	end
else
Camera.CameraType = Enum.CameraType.Scriptable

end

Hi it seems like you forgot an end!

Here is the fixed version:

RunService:RenderStepped:Connect(function()
	if Detected == false and Chatting == false then
	    for i, NPC in pairs(NPCS:GetChildren()) do
	        local Humanoid = NPC:FindFirstChild("Humanoid")
	        local HMR = NPC:FindFirstChild("HumanoidRootPart")
	
	        if Humanoid and HMR then
	            if (HMR.Position - CharHMR.Position).magnitude < 15 then
	                Detected = true
	                DetectedNPC = NPC
	                PromptLabel:TweenSize(UDim2(0, 60, 0, 60), "In", "Linear")
	                print(DetectedNPC.Name) 
	
	            end
	        end         
	    end
	end
	
	if Detected == true and Chatting == false then
	    local Humanoid = DetectedNPC:FindFirstChild("Humanoid")
	    local HMR = DetectedNPC:FindFistChild("HumanoidRootPart")
	
	    if Humanoid and HMR then
	        if (HMR.Position - CharHMR.Position).magnitude > 15 then
	            Detected = false
	            DetectedNPC = nil
	                PromptLabel:TweenSize(UDim2(0, 0, 0, 0), "Out", "Linear")
	            print("none npc detected you probaly are talking with air :D (someone really read this?)")
	        else
	                local WTPS = Camera:WorldToScreenPoint(HMR.Position)
	                PromptLabel.Position = UDim2.new(0, WTSP.X, 0, WTPS.Y)
	    	end
		end
	end
end)
