Why can I not read this challenge table?

local comMod= script.Parent:WaitForChild('ModuleScript');
local background = comMod.WaitForChild(script.Parent, 'background');
local main = comMod.WaitForChild(script.Parent.Parent, 'Main');
local questButton = comMod.WaitForChild(background, 'quests');
local questFrame = comMod.WaitForChild(main, 'questFrame');
local challengeFolder = comMod.WaitForChild(main, 'Challenges');
local challenges = {};

---// variables am i rite

function insertChallenge(challenge)
	print('adding '..challenge..' to the Challenges Table!');
	local amount = #challenges
	table.insert(challenges, (amount+1), challenge)
	print(challenges[amount+1]);
	return challenges[amount+1];
end

function removeChallenge(number)
	table.remove(challenges, number)
	return true;
end

function updateChallenges()
	for i = 1,#challengeFolder:GetChildren() do
		wait();
		local name = challengeFolder:GetChildren()[i].Name
		print(challenges[i]);
		if challenges[i] == name then
			print(name..' is already in the Challenge Table!');
			return true;
		elseif challenges[i] ~= name then
			print(name..' does not exist in the Challenge Table, adding it now!');
			insertChallenge(name);
			return challenges.name;
		end
	end
	end
	



questButton.MouseButton1Click:connect(function()
	script.Disabled = true;
	updateChallenges();
	questFrame.Visible = not questFrame.Visible
	script.Disabled = false;
end)

So, for some reason in the 3rd function, updateChallenges(), whenver I check to see if the challenge is already in the table, it will not read it and say it is not in the table?
