Why won't the script work?

Hey! So I was working on this game, and I decided to combine the main script of my game and this random kill script I found. I know the kill script works, but it won’t work once they are combined.
Kill script:

Could you tell me why it doesn’t add a point whenever someone gets a kill?

In the first script, maybe there “creator” is nil?

No, there are no problems in the output.

Your script.Parent where leaderstats, in the ServerScriptService?

Yeah the script it in ServerScriptService. The kill script is supposed to be in the workspace, but I don’t think it makes a difference if it is in the ServerScriptService or workspace.
