Trouble with weapon ammo.

[NnyAskC]

Needless to say this is my first time making something.

I was working from some template I found, loads fine and no errors or anything, but when I press the button to fire it just goes *click*.

Any help?

 AddCSLuaFile("shared.lua")
end

 killicon.AddFont("weapon_physcannon", "CSKillIcons", SWEP.IconLetter, Color(255, 80, 0, 255))
