Custom ULX command to work with Pointshop 2

[covey88]

So I recently installed pointshop 2 onto my Prop Hunt server.

With the old pointshop, I had a custom command that would give hunters a grenade (It worked through Pointshop because the grenade cost points.)

But now I'm needing to re-write the code to work with Pointshop 2.

Just wanting to see if anyone here can help me out before I go pay money for a simple code.

Here's the code that worked with the old pointshop.

[lua]local CATEGORY_NAME = "Utility"
local PRICE = (750) --- Price per nade.
local INVALID_RANK = ("You don't have access to that feature") --- Notifies player if they aren't in the correct rank.
local NOT_ENOUGH_POINTS = ("You can't afford nades") --- Notifies player they don't have enough points.
local INVALID_TEAM = ("You must be a hunter to buy nades.") --- Notifies player if they are on Props team.

function ulx.buy( calling_ply, num )

local ranks = {
["superadmin"] = true,
["admin"] = true,
["user"] = true,
["Owner"] = true,
["Admin"] = true,
["VIP"] = true,
["custom rank"] = true,

}
if ranks[calling_ply:GetUserGroup()] then
if calling_ply:Team() == TEAM_PROPS then
calling_ply:PS_Notify(INVALID_TEAM)
return
else
if calling_ply:Team() == TEAM_HUNTERS then
if not calling_ply:PS_HasPoints(PRICE) then
calling_ply:PS_Notify(NOT_ENOUGH_POINTS)
return
else
for i=1,num do
if calling_ply:PS_HasPoints(PRICE) then
calling_ply:PS_TakePoints(PRICE)
calling_ply:Give( "item_ar2_grenade" )
else
calling_ply:PS_Notify(" ")
return
end
end
end
end
end
else
calling_ply:PS_Notify(INVALID_RANK)
return
end

end

local buy = ulx.command( CATEGORY_NAME, "ulx buy", ulx.buy, "!buy" )
buy:addParam{ type=ULib.cmds.NumArg, min=1, max=100, default=1, hint="Number of nades", ULib.cmds.optional, ULib.cmds.round }
buy:defaultAccess( ULib.ACCESS_ALL)
buy:help( "Buys nades" )[/lua]

Any help is appreciated.
