I made my first SWEP

So I made my first SWEP, Because I would like to start contributing to Gmod
instead of leaching. So I made this Scar with Notepad Plus and Swep Creator.
I like some tips or advice on SWEPs.

If I did wrong or it is not working please tell me!

You seriously didnt test if it was working before you uploaded it?

Yeah I tested it on my garrysmod and it was working.
