NutScript Troubles

I’ll be honest, I’m not terribly familiar with GMod, or server running. I figured I’d learn as I go. It’s a bit more difficult than I’d imagined. Here is what I know. Screenshots and more information can be provided on request. I’m attempting to run a custom Schema.
I can’t use NS Rcon commands
It has the default HL2 GUI for weapon selection
It has the default Source engine chatbox
another thing I want removed but I’m unsure where to locat eit (It’s when Dr. Breen speaks when you first log on the server.)

Are there errors?
