Infinite Loop Detected

I am new to UE4 and I am using a tutorial on how to make a player stat system for health.
When I press play, it gives me an error ( ) I can not find any problems myself.
I tried re-doing the tutorial and It doesn’t seem to work. I’m going to provide some screenshots to show what the blueprints it tells me have infinite loops.

Get Stat is the only problem as what I can see.
I would appreciate if somebody could help! Thanks!
