ok so here is the script:

local Button = script.Parent
local Player = game:GetService("Players").LocalPlayer
local UserInput = game:GetService("UserInputService")
local canclick = true
script.Parent.MouseButton1Down:connect(function()
    if Player:FindFirstChild("Points").Value > 0 and canclick then
        Player.Strength.Value = Player.Strength.Value + 1
        Player.Points.Value = Player.Points.Value - 1
        wait(0.1)
        canclick = true
    end
end)
