I'm developing a server
This is what appears but I have no clue what is wrong the entire code itself is correct but does not seem to work I have categories
this is a job code I have

TEAM_BADGUY = DarkRP.createJob("Terrorist", {
color = Color(255, 0, 31, 255),
model = {"models/characters/osama_bin_laden.mdl"},
description = [[You Are A Terrorist be Terrible Permission: /advert Terror every 10minuts items.C4]],
weapons = {"keys", "pocket", "gmod_tool", "weapon_physgun", "m9k_suicide_bomb"},
command = "boom",
max = 4,
salary = 50,
admin = 0,
vote = true,
hasLicense = false,
candemote = false,
category = "Custom",
PlayerSpawn = function(ply)
ply:SetMaxHealth(100)
ply:SetHealth(100)
end,
customCheck = function(ply) return CLIENT or table.HasValue({Team_Misc}, ply:Team()) end,
CustomCheckFailMsg = "BOOBS4"
})
this is a categorie
DarkRP.createCategory{

name = "Category",

categorises = "jobs",

startExpanded = true,

color = Color(200, 20, 20, 255),

canSee = function(ply) return true end,

sortOrder = 100,

}
