Admins, remove this question?

I can't find these bugs, hoping you guys will be able to. This is in a Local Script, in the Player's PlayerGui

A - It won't show notes upon aiming at doors, though if E is press, acts like normal (Still no note) B - Won't Examine objects

Here is an image of the Hierarchy - http://prntscr.com/3cg8fm

Is it possible that it's not the script, and just your setup of the hierarchy? (That a value is false when it should be true by default, or vice versa)

It looks like the code SHOULD work. The best way to debug is to add print("Test #[NUMBER]") or something like that, to see where it doesn't go when it should.
