NPC Quest Script - Value Not Updating Correctly?

Hello, I am working on an NPC quest script that relies on instances of number values to inform the script what information to display in a chat GUI for said script. It seems as though this value is only changing within the script, but not the game itself.

The NPC is being cloned from within a folder in this local script, which resides in the StarterPlayerScripts tab.

Here is the script itself:

wait(2)

local Player = game.Players.LocalPlayer

local PlayerGui = Player.PlayerGui

local PlayerCharacter = game.Workspace[Player.Name]

local Children = PlayerCharacter:GetChildren()

local WaitToTouch = false

for i,v in pairs(Children) do
	wait()
	if v.ClassName == "Part" then
		v.Touched:Connect(function(Touched)
			if WaitToTouch == false then
				if Touched.Name == "FriendlyTouch" then
					WaitToTouch = true
					print(Touched)
					if Touched.Parent.Quests then

						local Quests = Touched.Parent.Quests

						local QuestID = Quests.QuestID.Value
						local CurrentQuest = Quests["Quest"..QuestID]

						local QuestPartID = CurrentQuest.QuestPartID.Value

						local CurrentPart = CurrentQuest["Part"..QuestPartID]

						if CurrentPart then
							if CurrentPart.Chat then
								local CurrentQuestPartChat = CurrentPart.Chat
								local NPCChatGui = PlayerGui.NPCChatGui
								local NPCChatGuiName = NPCChatGui.Frame.NPCName
								local NPCChatGuiText = NPCChatGui.Frame.NPCText
								NPCChatGuiName.Text = Touched.Parent.Name
								NPCChatGuiText.Text = CurrentQuestPartChat.Value
								NPCChatGui.Frame.NPCText.MouseButton1Down:Connect(function(Clicked)
									QuestPartID = QuestPartID + 1
									print(QuestPartID)
									print(CurrentPart)
									NPCChatGuiName.Text = "[NPC_Name]"
									NPCChatGuiText.Text = "[NPC_Text]"
									WaitToTouch = false
								end)
							end
						end
					end
				end
			end
		end)
	end
end

Here is the output:

Thank you in advance for your help!

Okay, In case anyone has a similar issue, I figured it out. It seems there is some limitation with how many variables ROBLOX can pass data through. I changed line 41 to the following:

Touched.Parent.Quests["Quest"..QuestID].QuestPartID.Value = Touched.Parent.Quests["Quest"..QuestID].QuestPartID.Value + 1

I also had no debounce for clicking on the GUI button, which caused the script to add to the value in a weird way. After having committed both of these changes, this issue is now completely resolved.
