Unclear issues with a script

So I've been working on mcreator for about two days to make a "The Last of Us" mod, and I've run into an issue. 
This is a right click script for a "Shiv" item that instantly kills my Runner and Clicker entities.
It works as intended for my Clicker entity, but has no effect on my Runner.

Above was my first script,
Here is my second
I would like some help with this expediently, no rudeness intended.
