Admin Script Issues?

I have purchased a model of an admin script and it is fully written and everything. At least it looks that way to me since I am only a beginner scripter and can only write a single kill command. Anyways, its not working. I put the script in the game/workspace and added the names to who I wanted to have admin (me and some of my best friends), but when I tested it in the live Roblox it wouldn't work, what could have gone wrong?

Who's admin is it? What exactly isn't working? I need to know before I can properly help you.

Did you say the proper command? kill/
