How to detect collision between two players (Multiplayer)

so I started my first game.
I’m trying to create a game like but in 3D.
so basically I need to detect if on collision 1 player is bigger than the other (I Tried using hamburgers as counting) XD
but, I just can’t figure out how do I compare different players (Because they are using the same blueprint) and when I call the “Hamburger Variable” I get the same Variable
Might be a stupid question but I would love some help

I Know this isn’t how to do it (Because I’m comparing the same variable) but maybe it will make my question clearer

Solved - I’m dumb.
Just need to take the “Hamburger” form the casted character
