Patty = game.Lighting.KrabbyPatty
Tripple = game.Lighting.TripleKrabbyPatty
Double = game.Lighting.DoubleKrabbyPatty
function KrabbyPatty(player, choice)
	if choice.Name == "DoubleKrabbyPatty" then
	Double:Clone()
	Double.Parent = player.Backpack
wait()
	
elseif choice.Name == "TheKrabbyPatty" then
		Patty:Clone()
		Patty.Parent = player.Backpack
	elseif choice.Name == "TrippleKrabbyPatty" then
		Tripple:Clone()
		Tripple.Parent = player.Backpack	
	
	
	end
end

script.Parent.Dialog.DialogChoiceSelected:connect(KrabbyPatty)

Whenever I click the 'same' dialog twice it runs this error. The Parent property of KrabbyPatty is locked, current parent: NULL, new parent Backpack

What does that mean and how do I fix this?
