You're running the file serverside.

I am a "noob" in lua, what does that mean :P

[koolaidmini]

Google "Gmod Clientside" and "Gmod Serverside".

As i said i don't know LUA, I just searched it and i got much stuff i don't even understand...

Move the function to some clientside file and do some networking and/or just add "if SERVER then return end" at top of it.

There is the server, which deals as expected on the server, and the client, which means what's run on your computer. This all gets confusing when in single player, but it's simple actually. Basicly, you file is being included by an init.lua file in your gamemode I'm guessing. Instead, include it in the cl_init.lua and make sure to AddCSLuaFile the file from the init.lua

Wow dude, finally someone who can explain something to a newbie :P Thanks alot it helped, I just Removed include("cl_start.lua") from init.lua and added it to cl_init.lua, I keeped the AddCSLuaFile in Init.lua and it works :D
