You'd have to show that part of your script for us to help you. If you do not provide this information, it will be impossible for us to help you, except for that we download it, but that's nothing we should need to do.
We're here to help you, not to do the things for you.
I don't think anyone around here would put the effort to download the gamemode/admin-system and check it out, so, as mentioned, you should show the code.
