Incrementing of table not working

[MyDimeIsUp]

Trying to use this code to detect if a car is in a certain spawn location, and if there is, to try the next location. Doesn't seem to be working. I keep getting this error

Here is my table code:
  SGMRP.vehicles.npc["Bus"] = {
    title = "RTA",
    model = "models/suits/male_0" .. math.random(1, 9) .. "_closed_tie.mdl",
    pos = Vector(-1084.092529, 4282.931152, 608.031250),
    ang = Angle(0, 90, 0),
    teams = {
      [TEAM_BUSDRIVER] = true
    },
    spawn = {
      [1] = {
        pos = Vector(-1450.528687, 4477.806152, 600.031250),
        ang = Angle(0, 0, 0)
      },
      [2] = {
        pos = Vector(-831.973022, 4006.948242, 600.031250),
        ang = Angle(0, 90, 0)
      }
    }
  } 
Here is the code to check the spawn points

for k, v in pairs(SGMRP.vehicles.npc[npc:GetNPCKey()]) do
    for kV, vV in pairs(ents.FindInSphere(v[tCount].pos, 1000)) do
      if !vV:IsVehicle() then
        car:SetAngles(v[tCount].ang)
        car:SetPos(v[tCount].pos)
      elseif vV:IsVehicle() then
        print("car in area")

        if v[tCount + 1] == nil then
          print("No spanws left")
          SGMRP.Notify(ply, "No more spawn locations. Try again in a bit", 1, 5)
        else
          print("before", tCount)
          tCount = tCount + 1
          print("after", tCount)
          continue
        end
      end
    end
  end

Any ideas why I'm getting this error? Thanks

From the looks of that code, you're probably trying to do:
for k, v in pairs(SGMRP.vehicles.npc[npc:GetNPCKey()].spawn) do
rather than the first line in that snippet because in that code you're getting (title, model, pos, ...) as the 'k' and the corresponding value as v

I don't think I can do that because I want to check all spawn points, and when there are no free spawnpoints, to let the user know. How would I do it that way?

Ah I see, I tried to answer without actually trying to see what it is you were trying to do.
Anyway here's what I figure you want to do:
local found_spawn = false
for k, v in pairs(SGMRP.vehicles.npc[npc:GetNPCKey()].spawn) do --Iterate over every spawn location
local has_vehicle = false
for kV, vV in pairs(ents.FindInSphere(v.pos, 1000)) do --Find cars in the spawn
if vV:IsVehicle() then
has_vehicle = true --If you find one, set this to true to indicate it's used
break
end
end
if not has_vehicle then -- If the var wasn't set to true then the spawn is available
found_spawn = true --Set this to true to indicate you found a spawn
--Do your stuff here
break
end
end
if not found_spawn then
--There's no spawns left
end
Let me know if I understood wrong

Works. Thanks very much for the help!
