Multiplayer health won't show up

I’ve been having some trouble displaying health for some reason. This should literally be the easiest task ever, and I’ve done it several times, even on multiplayer projects. I’m pretty new though, so maybe I made a dumb mistake.

Here is my old code:
(in the widget)


(in the player)

and here is the new code that isn’t working:

Literally the only thing that is different is that some of the variables are replicated, but even when they aren’t replicated, it doesn’t work. the widget is NOT showing up, either; image
Even though I have the widget class correct.

Any help is appreciated. Thank you!
