I tried to make it so when u got the certain tool then ur value goes +100 when u touched it. Help?

--This is a normal script

local db = true

script.Parent.Touched:connect(function(hit)
    if hit.Parent:FindFirstChild("Humanoid") ~=nil then
        if db == true then
            db = false
            script.Parent.Transparency = 1
            local player = game.Players:GetPlayerFromCharacter(hit.Parent)
            game.Players.LocalPlayer.Character.BackPack:WaitForChild("Hamburger")
            player.leaderstats.Candy.Value = player.leaderstats.Candy.Value + 100
            script.Sound:Play()
            script.Parent:Destroy()


end
end


end)
