Cant use my SWEP in Garry's Mod?

I spent about a hour trying to figure this out but still cant, basically my weapon(based off the chair throwing gun tutorial) wont show up in the Q menu. I tryed using SWEP.Category but no luck. Here is the code: http://pastebin.com/Tz3b2gwU

I also did this in lua/ and then created a folder for it.

Thanks for the help!

Your folder structure needs to be addons/customfoldername/lua/weapons

Still no luck, am I missing a file? I just made a Addon.txt file , ill see if that works…
