Why did my door script stop working all of a sudden?

So I have a house system that when you click a door you purchase a house(you pay some money, the owner stringvalue's value gets changed to your name) and when you touch the door, it opens it up. Everything worked fine until the last update I made where I added some furniture to the house. Nothing else. No script changes. Any idea why? Here's the code:

owner = script.Parent.Parent:WaitForChild("Owner")

script.Parent.Touched:Connect(function(hit)
    if hit.Parent:FindFirstChild("Humanoid") then
        print("There's a Humanoid")
        if hit.Parent.Name == owner.Value then
            print("It's the owner")
            script.Parent.Transparency = 0.5
            script.Parent.CanCollide = false
            print("Door open")
            wait(5)
            script.Parent.Transparency = 0
            script.Parent.CanCollide = true
            print("Door close")
        end
    end
end)

It doesn't even print "There's a Humanoid".
