Why doesn't my MouseButton1Click function fire?

Ok so I made probably the most basic placeholder script for my UIs.

script.Parent.MouseButton1Click:Connect(function()
	print("entered!")
end)

The parent is a TextButton under a ScreenGUI in StarterGUI. Won't fire at all, even though it's just a print statement. Would appreciate some guidance here. Thanks in advance if you can help...

EDIT: I completely forgot that it needs to be local. That's what I get for stop using lua for 3 months.

You need to use a LocalScript.
