Custom Command Help

[MentallyAdvanced]

Well, Im making a gamemode and I get an error, even though Im sure it is right, so I need help.

function buyEntity (ply, cmd, args)
	if(args[1] !=nil) then
		local ent = ent.Create(args[1])
		local tr = ply:GetEyeTrace()
		
		if(ent:IsVaild())then
		local ClassName = ent:GetClass
		
		if(!tr.Hit)then return end
			
		local entCount = ply:GetNWInt(ClassName .. "count")
			
		if(entCount <  ent.Limit)then
			local SpawnPos = ply:GetShootPos() + ply:GetForward() *80
			
			ent.Owner = ply
			
			local ent = ents.Create(ClassName)
			ent:SetPos(SpawnPos)
			ent:Spawn
			ent:Activate
			
			ply:SetNWInt(ClassName .. "count", entCount + 1)
			return ent
		end
		return
		end
	end
end

concommand.Add("buy_entity", buyEntity)

I'm not an expert, but did you forget an end here?

if(ent:IsVaild())then
    local ClassName = ent:GetClass
end -- Right here?

Change

local ClassName = ent:GetClass

to

local ClassName = ent:GetClass()

You've done the same thing multiple times later on. If you want to call a function you must use () even if it has no arguments
