My script I made is not really working at all! Can you see what's wrong? [closed]

here is my code :

local debounce = true

script.Parent.Touched:Connect(function(hit)
    if debounce == true then    
        if hit.Parent:FindFirstChild("Humanoid") then

            local char = hit.Parent
            local player =  game.Players:GetPlayerFromCharacter(char)
--//------------------------------------------------------------------------------------------------------------------------------------------\\--
            print("Sold!")
            debounce = false
            player.leaderstats.Cash.Value = player.leaderstats.Cash.Value + player.Knowledge.Value
            player.Knowledge.Value = 0
            wait(1)
            debounce = true
        end
    end
end)
