Probleme ajout d'arme vendeur d'arme

[Yoko6001]

Bonjour,j'ai un soucis lorsque j'ajoute ceci a shipment pour avoir acheter l'arme avec le vendeur d'arme
DarkRP.createShipment("Ak47", {
model = "models/weapons/w_rif_ak47.mdl",
entity = "m9k_ak47",
price = 10000,
amount = 10,
seperate = false,
pricesep = nil,
noship = false,
allowed = {TEAM_GUN}
})

j'ai cet erreur en jeu
[ERROR] A runtime error has occurred in "your custom shipments" on line -1.
The best help I can give you is this:

The category of "Ak47" ("Other") does not exist!

Hints:
- Make sure the category is created with DarkRP.createCategory.
- The category name is case sensitive!
- Categories must be created before DarkRP finished loading.

The responsibility for the error above lies with (the authors of) one (or more) of these files:
your custom shipments
------- End of Simplerr error -------

quelqu'un serait comment la régler? Merci d'avance
