Help with a gladiators 1v1 script, why isn't it working?

So, I have a gladiators 1v1 script that works fine except for a few things:

1. When 1 player kills the other, it does not add 1 to the plrs number value kill value
2. it only works once right now, I want it to keep going until a button is clicked
3. if you decide to fix this, a few things: 1. don't change the script to much, 2: don't add in the end when a button is clicked part, I can add that in myself
