Need Help with Party System

[aomsinz800i (Exitium)]

Hello! This is my first time trying to do this system. I was modifying HowToRoblox’s Party System. I modify it to be able to choose Arc —> chapter(1-10) and it work! but the problem start to arrive.

Problem Line 90 - 94: I’m not sure why currentSelectChapter and currentListChap keep returning nil result in “No Chapter Selected” if someone can point out what did I do wrong, please.

How to Make a PARTY MATCHMAKING SYSTEM in ROBLOX!

Thank you for reply!

if this can help you!

[Maratyla10 (Maratyla)]

bro, did you notice that local open and local close are blue colored (that means its a roblox system variable) like local wont work if u put something from roblox. ex: local wait = 1

Rename locals into another name, like close to closeparty and open to openparty

[aomsinz800i (Exitium)]

that is not the problem… also I don’t know why it is blue in this

[Maratyla10 (Maratyla)]

switch the locals’s names so they turn white and modify the script to correct them to new locals, and try running the script

[aomsinz800i (Exitium)]

are you sure that we are talking about ChapterLabel?

[aomsinz800i (Exitium)]

[aomsinz800i (Exitium)]

more info: It is a nil to other player except owner

[Maratyla10 (Maratyla)]

i may have found the problem: did you make the system which changes the nil to another value?

[aomsinz800i (Exitium)]

please elaborate that

[aomsinz800i (Exitium)]

these part?

function displayChapter(RequireChap)
	lastSelectedChapter = RequireChap.Name  

	displayPage(main.Chapter)
	main.Chapter.Title.Text = lastSelectedChapter

	currentSelectChapter = RequireChap

	for i, chapterButton in pairs(main.Chapter:GetChildren()) do
		if chapterButton:IsA("TextButton") then
			chapterButton.MouseButton1Click:Connect(function()
				runOnce(function() 
					displayListChap(chapterButton) 
				end, "displayListChap")
			end)
		end
	end
end

function displayListChap(RequireChap)
	displayPage(main.ListChap)
	main.ListChap.Title.Text = RequireChap.Name

	currentListChap = RequireChap
end

[aomsinz800i (Exitium)]

If it was these then I need it to send to server to change mapid, but I don’t think these are the cause of problem

[Maratyla10 (Maratyla)]

Only thing i found in your script that is you are making these locals and not changing the set variable then checking if chapter selected

[aomsinz800i (Exitium)]

oh yeah It might be that. I will change some part real quick

[aomsinz800i (Exitium)]

so weird

        print("Selected Chapter: " .. currentSelectChapter.Name)
		print("Selected List: " .. currentListChap.Name) 

it did print something except nil(both server and client)

[aomsinz800i (Exitium)]

Help me

[Maratyla10 (Maratyla)]

Rule 1: if it works, dont touch it

[aomsinz800i (Exitium)]

so true

[aomsinz800i (Exitium)]

I finally done it I add new value called Arc and Chapter. IT WORK!

[Maratyla10 (Maratyla)]

did it make your script better by telling you that you forgot to change values from nil?
