How do I make player not able to jump?

function OnEntered(Player)
	while Player.Character == nil do
		wait()
	end
end
function OnRespawned(Character)
	local Torso = Character:findFirstChild("Torso")
	if Torso ~= nil then
		local AntiJump = Instance.new("BodyPosition")
		AntiJump.Parent = Torso
		AntiJump.position = Vector3.new (0,6,0)
		AntiJump.maxForce = Vector3.new (0,10000000000,0)
	end
end
game.Players.ChildAdded:connect(OnEntered)
game.Workspace.ChildAdded:connect(OnRespawned)

I have been using this script and you are still able to jump. Could anyone fix this so no players will be able to jump?
