why doesn't this script work on the gui when i click on a button?

So I have a daily rewards gui and when I click the claim it should give rewards but the script is functioning properly? Any clues?

local folder = script.Settings
local rewardDebounce = folder.RewardTime.Value
local ls = folder.LeaderStatsEnabled
local lsName = ls:WaitForChild("Name")
local lsValue = ls:WaitForChild("Reward")

function reward(p)
	if ls == true then
		local find = p:FindFirstChild("leaderstats")
		if find then
			local val = find:FindFirstChild(lsName.Value)
			if type(val) == "number" then
				val.Value = val.Value + lsValue.Value
			end
		end
	end
end

local ds = game:GetService("DataStoreService"):GetDataStore("DailyReward")

function ending(text)
	print(text)
	local e = string.sub(text,string.len(text)-3)
	if tonumber(lsValue.Value) ~= 1 and e == "(%.+)e" then
		text = text.. "s"
	end
	return text
end

function give(key,p)
	repeat wait() until p.Character
	wait(2)
	local gui = script.DailyRewardGui:Clone()
	gui.Parent = p.PlayerGui
	if ls.Value == true then
		gui.main.text.Text = lsValue.Value.. " " ..ending(lsName.Value).."!"
	else
		gui.main.text:Destroy()
		gui.main.title.Text = "You got your daily reward!"
		gui.main.title.FontSize = Enum.FontSize.Size24
		gui.main.title.Size = UDim2.new(1,0,0.7,0)
	end
	repeat wait() until gui.done.Value == true
	print("Giving reward to " ..p.Name)
	ds:SetAsync(key,os.time())
	reward(p)
end

function setup(key)
	local t
	local success,msg = pcall(function() t = ds:GetAsync(key) end)
	if not success then
		warn("New player..")
		t = os.time() - rewardDebounce
	elseif type(t) ~= "number" then
		warn("Error, resetting..")
		t = os.time() - rewardDebounce
	else
		warn("DataStore retrieval successful (daily reward script)")
	end
	return t
end

function checkReady(key,t,p)
	local newTime = os.time()
	local secs = newTime - t
	if secs >= rewardDebounce then
		print(p.Name.. " has an unclaimed reward!")
		give(key,p)
	else
		print(p.Name.. " has already had a reward today!")
	end
end

game.Players.PlayerAdded:connect(function(p)
	local key = "user_" ..p.UserId
	local lastPlayed = setup(key)
	print(lastPlayed.. " vs. " ..os.time())
	checkReady(key,lastPlayed,p)
end)
