How to make a item that give you a random leaderstats value when you click?

local price = 1
local db = true
local Strings = {'Scrap', 'Plank','Rubber'}
local x = Strings[math.random(1, #Strings)]
print(x)

script.Parent.ClickDetector.MouseClick:connect(function(player)
    player.hiddenstats:FindFirstChild(x).Value = player.hiddenstats:FindFirstChild(x).Value + price
    db = false
    script.Parent.Transparency = 1
    script.Parent.CanCollide = false
    wait(75)
    script.Parent.Transparency = 0
    script.Parent.CanCollide = true
    db = true
end
end)

this is my script for it
