How can I make my Remote Event create TextButtons Online?

I'm having trouble making a script that uses a Remote Event work Online. It works fine in studio, but nothing happens elsewhere. I'm using a Remote Event because scripting without this did not work either. I'm just trying to create 3 TextButtons, nothing more. Any and all help is appreciated.

P.S Please don't direct to the "It works fine in Studio but not online" page.

Server Script:

script.Parent.Order.MouseButton1Click:connect(function()
	Events.OrderParts:FireServer()
end)

Remote Event:

script.Parent.OnServerEvent:connect(function()
	local TextButton1 = Instance.new("TextButton", script.Parent.Parent.Parent)
	local TextButton2 = Instance.new("TextButton", script.Parent.Parent.Parent)
	local TextButton3 = Instance.new("TextButton", script.Parent.Parent.Parent)
	
	TextButton1.Text = "Order CPU's"
	TextButton1.TextColor3 = Color3.new(255, 255, 255)
	TextButton1.Font = Enum.Font.SourceSansItalic
	TextButton1.BackgroundTransparency = 0.8
	TextButton1.Position = UDim2.new(0.8, 0,0.2, 0)
	TextButton1.Size = UDim2.new(0, 200,0.05, 50)
	TextButton1.TextScaled = true
	TextButton1.Name = "OrderCPU"
	
	TextButton2.Text = "Order Cases"
	TextButton2.TextColor3 = Color3.new(255, 255, 255)
	TextButton2.Font = Enum.Font.SourceSansItalic
	TextButton2.BackgroundTransparency = 0.8
	TextButton2.Position = UDim2.new(0.8, 0,0.35, 0)
	TextButton2.Size = UDim2.new(0, 200,0.05, 50)
	TextButton2.TextScaled = true
	TextButton2.Name = "Ordercase"
	
	TextButton3.Text = "Cancel"
	TextButton3.TextColor3 = Color3.new(255,255,255)
	TextButton3.Font = Enum.Font.SourceSansItalic
	TextButton3.BackgroundTransparency = 0.8
	TextButton3.Position = UDim2.new(0.53, 0,0.27, 0)
	TextButton3.Size = UDim2.new(0, 200, 0.05, 50)
	TextButton3.TextScaled = true
	TextButton3.Name = "Cancel"
end)
