Text Label Scroller/Selector Displays values in wrong order and gets stuck?

local list = {"Aunt","Big","Cap'n","Captain","Chef","Chief","Coach",
"Colonel","Cool","Crazy","Daring","Deputy","Dippy","Doctor","Dr.","Elvin","Elvis",
"Eddy","Earl","Fancy","Fat","Good ol'","Grand ol'","Granny","Grumpy","Judge","Lady","Little","Loopy",
"Loud","Lucky","Madame","Miss","Mrs.","Noisy","Princess","Prof.","Queen","Sheriff","Silly","Skinny",
"Super","Ugly","Weird"}

local titledown = script.Parent.TitleDown
local titleup = script.Parent.TitleUp
local curNum = 4 -- since we have start in the middle use 2
local max = #list

-- ref to the text labels all in order
local txt3 = script.Parent.TitleUp.Name_3-- This is ontop = top text label
local txt2 = script.Parent.TitleUp.Name_2
local txt1 = script.Parent.TitleUp.Name_1
local txt0 = script.Parent.TitleUp.Name0-- this is the middle text label
local txt_1 = script.Parent.TitleUp.Name1
local txt_2 = script.Parent.TitleUp.Name2-- This is below = bottom text label

function showTxt()
	txt0.Text = list[curNum] -- the middle will always be accessible
	txt2.Text = list[curNum + 2]
	txt1.Text = list[curNum + 1]
	txt_1.Text = list[curNum - 6]
	-- some more advanced method	
	-- txt1.Text = list[curNum - 1] and list[curNum - 1] or list[max] 
	-- un tested but it used the logic shown here https://www.lua.org/pil/3.3.html	
	
	if list[curNum - 1] == nil then -- wouk out is we can do the logic
		txt3.Text = list[max] 
	else
		txt3.Text = list[curNum - 1]
	end
	
	if list[curNum + 1] == nil then 
		txt_2.Text = list[1] 
	else
		txt_2.Text = list[curNum + 1]
	end
	
end
	

titleup.MouseButton1Click:connect(function()
	curNum = curNum + 1
	if curNum > max then curNum = 1 end -- reset our number
	showTxt() -- update the text
end)

titledown.MouseButton1Click:connect(function()
	curNum = curNum - 1
	if curNum <= 0 then curNum = max end -- again the reset
	showTxt()
end)

showTxt()

Not sure what i did wrong here Kingdom5 but its not avting like it should anymore cri

This code should work. Sorry if it doesn't, I can't test it right now.

local list = {"Aunt","Big","Cap'n","Captain","Chef","Chief","Coach",
"Colonel","Cool","Crazy","Daring","Deputy","Dippy","Doctor","Dr.","Elvin","Elvis",
"Eddy","Earl","Fancy","Fat","Good ol'","Grand ol'","Granny","Grumpy","Judge","Lady","Little","Loopy",
"Loud","Lucky","Madame","Miss","Mrs.","Noisy","Princess","Prof.","Queen","Sheriff","Silly","Skinny",
"Super","Ugly","Weird"}

local titledown = script.Parent.TitleDown
local titleup = script.Parent.TitleUp
local curNum = 1

local labels = {}
for _,v in pairs (titleup:GetChildren()) do
	local num = tonumber(string.match(v.Name,"(%d+)") or string.match(v.Name,"-%d+")) -- finds the number of the label
	if num then
		labels[num] = v
	end
end

function showText()
	for i = -2,2 do -- iterates the through the labels
		labels[i].Text = list[curNum+i] or list[#list-i] or list[#list+i] -- sets the text, first catering for the middle label, then the upper ones, then the lower ones
	end
end

titleup.MouseButton1Click:connect(function()
    curNum = curNum + 1
    if curNum > #list then curNum = 1 end -- reset our number
    showTxt() -- update the text
end)

titledown.MouseButton1Click:connect(function()
    curNum = curNum - 1
    if curNum <= 0 then curNum = #list end -- again the reset
    showText()
end)

showText()

Hope I helped!
