Why doesn't this script work? Torso is not a valid member of Model?

Hello. I tried to make a part that gives you an antigravity effect when you touch it; but it prints out an error: "Torso is not a valid member of model".

enabled = true

script.Parent.Touched:Connect(function(hit)
	if hit.Parent:FindFirstChild('Humanoid') and enabled then
		enabled = false
		local bodyForce = Instance.new("BodyForce", hit.Parent.Torso)
		bodyForce.Force = Vector3.new(0,1000,0)
	end
end)

Hey, may you tell me the type of character your game is? R6 or R15?
