Child Added script is not working as I intended. Help??

Here's the script.

while wait(3) do
	if script.Parent.ChildAdded:Connect() then
		script.Parent.Group.Parent = script.Parent.Parent["Waiter/Waitress Board"].TextButton.Page1.Order1
	end
end

It did not work.

Here's the output if you are willing to try and help me:

10:48:28.708 - Attempt to connect failed: Passed value is not a function

Thank you have a nice day.
