Unable to run lua scripts

Hello.

There seems to be a problem when I attempt to load a script via the Developer's Console.

For example, if I were to use the 'ttt3.lua' script, I'd place it in my common/GarrysMod/garrysmod/lua directory but to no avail, as this error always arises: couldn't include file 'ttt3.lua' (file not found) (<nowhere>)

Now, this question may seem rather repetitive, and there may be a sticky regarding the matter, however, upon initially researching, I was unable to find a solution regarding this problem.

Thank you for taking your time to read this.

so say you have a script named abc
you put it in the lua directory, then type lua_openscript_cl abc.lua
that should work, i'm pretty sure if it doesn't it's an error on your part
