[B]DARK RP "this weapon is unavalable" help.[/B]

[mehlel]

i added some weapons to my Dark RP server, but when i attempt to purchase them from the F4 menu it simply says that the weapon is unavailable. any ideas why this is happening?
some of them are from a mod called extra customizable weaponry.

here is the lua of the weapons i added:
