Frame is not valid member of frame?

I'm creating a give system which the barista sends the item to the player (cafe game) and a gui pops up saying yes, no, I didn't order that. It only works in-studio but not in-game. Error: http://prntscr.com/iz4gey Explorer objects: http://prntscr.com/iz4gom Inside the buttons are just localscripts.

script.Parent.Frame.Holder:TweenPosition(UDim2.new(0,0,0,0), "In", "Linear", .3, true)
script.Parent.AnswerHolder.y:TweenPosition(UDim2.new(0, 0,0.005, 0), "Out", "Linear", .3, true)
script.Parent.AnswerHolder.w:TweenPosition(UDim2.new(0, 0,0.717, 0), "Out", "Linear", .3, true)
script.Parent.AnswerHolder.n:TweenPosition(UDim2.new(0, 0,0.364, 0), "Out", "Linear", .3, true)
local barista = script.Parent.Parent:WaitForChild("barista")
local item = nil

for i,v in next, script.Parent.Parent:GetChildren() do
	if v.ClassName == "Tool" then
		if v:FindFirstChild("topbun") == nil then
			item = v
		else
			item = game.Lighting[v.Name]:Clone()
		end
	end
end
