Is this a Model or Lua error?

[Adam.]

Hey people, having a problem with Weapons D:

I've recently installed CSS Realistic Weapons 4, and it's working perfectly, although after installing it. The previous weapons i had, stopped working. (i.e. The weapons that come ready with Dark RP)

Here's my stun stick...

Now, besides the obvious first error (appearance), i'm also confused on the "SetWeaponHoldType"..
Note that this used to work before installed CSS Realistic Weapons.
I've tried a clean install without the CSSRW's pack, and the normal weapons still error like this.

Here's my code.

Thanks in advance!
