Inventory system tutorial help

I’ve been trying to follow this youtube tutorial (https://www.youtube.com/watch?v=yx3umVORujE) to create an inventory system but I’m running into trouble when it comes time to bring up the inventory widgets, specifically, the “grid” and the individual item “slots.”

This is my inventory slot BP:

My inventory grid BP:

My playermenu BP

My player controller BP

And my player HUD bp

I keep looking through the tutorial to try and see where mine might be different, but I can’jt figure anything out.
