Saving and loading arrays from game instance?

I gave it a shot, but I’m doing something wrong.

First do I want to put these nodes on my Character?

Should I use something other than an EventBeginPlay?

I have a save game file that contains all the variables you see on the left in this screenshot. I am trying to load certain ones when my player enters new levels, but it’s not loading anything.

What might I be doing wrong?
