Inventory System Not Functional

Hi there! Anyone out there willing to talk to me one on one to help me troubleshoot my inventory issues?
I’m using an Inventory System I got from a YouTube tutorial. I’ve used this system before in a first person map and it worked perfectly. I am now trying to implement the same thing in a TopDown Map. My first problem is that my slots do not show up in my inventory grid even though all the code is the same as before (unless I missed something I’m unaware of). On top of that I have an issue where in my first person game things added to inventory with an InputAction Event. In TopDown I’m not using that I want things to auto pick up as you “hit” the actor. My problem there is that when I add the “Add To Inventory” node to an actor I get an error saying the Inventory Component returned none.
Any help is greatly appreciated <3
