Need help with a HUD Problem

[DrVrej]

I want my HUD to show the weapon name but it is making this error in the console that shouldn't appear!

[Lua]
[ERROR] lua/includes/modules/draw.lua:263: attempt to index field 'pos' (a nil value)
1. Text - lua/includes/modules/draw.lua:263
2. v - addons/vj base/lua/autorun/vj_hud.lua:45
3. unknown - lua/includes/modules/hook.lua:82
[/Lua]

I tried this codes:
[Lua]
local client = LocalPlayer()
local weapon = client:GetActiveWeapon()
[/Lua]

Tried this one:
[Lua]
draw.SimpleText(weapon, "HudHintTextLarge", 1275, 980, Color(0, 255, 0, 255), 0, 0)
[/Lua]

Tried this:
[Lua]
draw.SimpleText(weapon.PrintName, "HudHintTextLarge", 1275, 980, Color(0, 255, 0, 255), 0, 0)
[/Lua]

Tried this:
[Lua]
draw.SimpleText(client:GetActiveWeapon(), "HudHintTextLarge", 1275, 980, Color(0, 255, 0, 255), 0, 0)
[/Lua]

Nothing is working! Please help!
