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)
