I am currently trying to see if I completely understand how the Debounce and seeing if the it's a player who touched the part. But when I run the script, it says attempt to call method 'Touched' (a userdata value)

Here's the code,

function OnTouched(part)
    Debounce = false
    player = part.Parent:FindFirstChild("Humanoid")
    if not player then
        player2 = player.Parent:FindFirstChild("Humanoid")
    end
    if not Debounce then
        Debounce = true
        if player or player2 then
            print("It worked!")
        end
        wait(3)
    end
    Debounce = false
end


script.Parent:Touched(OnTouch)
