Need HELP for Train Spawner GUI

I spawned a train with a good spawner GUI, but it was located at the centre position. Even, when I show output, it says “Argument 1 missing or nil” at line 16. So, however, I scripted and messed up for some train spawner GUI.

local plrEngine = {}
local spawnLocation = workspace.spawnLocation
local replicatedStorage = game.ReplicatedStorage
local spawnTrainEvent = replicatedStorage.SpawnTrainEvent

spawnTrainEvent.OnServerEvent:Connect(function(plr, engineAsset, slocation)
	
	-- Check if the player has already spawned a train
	if plrEngine[plr] then
		plrEngine[plr]:Destroy()
	end
	
	local engine = replicatedStorage.TrainAssets.Locomotives.Steam:FindFirstChild("Thomas"):Clone()
	engine.Parent = workspace
	
	local spawnLoc = slocation or spawnLocation:WaitForChild(slocation)
	engine:SetPrimaryPartCFrame(CFrame.new(spawnLoc))
	
	plrEngine[plr] = engine
	
end)

How do I make some trains spawn properly at the same position as the part I named “location” of them?

To ensure that the trains spawn at the same position as the part you named “location”, you can modify your code as follows:

local plrEngine = {}
local replicatedStorage = game.ReplicatedStorage
local spawnTrainEvent = replicatedStorage.SpawnTrainEvent

spawnTrainEvent.OnServerEvent:Connect(function(plr, engineAsset, slocation)
	
	-- Check if the player has already spawned a train
	if plrEngine[plr] then
		plrEngine[plr]:Destroy()
	end
	
	local engine = replicatedStorage.TrainAssets.Locomotives.Steam:FindFirstChild("Thomas"):Clone()
	engine.Parent = workspace
	
	local spawnLoc = slocation or workspace.spawnLocation -- Use workspace.spawnLocation directly if slocation is nil
	
	if spawnLoc then
		engine:SetPrimaryPartCFrame(CFrame.new(spawnLoc.Position))
		plrEngine[plr] = engine
	else
		warn("Spawn location not found!")
	end
	
end)

I’ve modified the spawn train script. Now for position from the selected location for value? Because ObjectValue doesn’t have CFrame values.

local plrEngine = {}
local replicatedStorage = game.ReplicatedStorage
local spawnTrainEvent = replicatedStorage.SpawnTrainEvent

spawnTrainEvent.OnServerEvent:Connect(function(plr, engineAsset, slocation)

	-- Check if the player has already spawned a train
	if plrEngine[plr] then
		--plrEngine[plr]:Destroy()
	end

	local engine = engineAsset
	
	if engine then
		engine:Clone().Parent = workspace
	else
		error("Unable to find engine asset!")
	end

	local spawnLoc = location or workspace.spawnLocation -- Use workspace.spawnLocation directly if slocation is nil

	if spawnLoc then
		engine:SetPrimaryPartCFrame(CFrame.new(spawnLoc.Position))
		plrEngine[plr] = engine
	elseif not spawnLoc then
		error("Unable to find spawn location!")
	elseif not spawnLoc:IsA("Basepart") then
		error("Failed to load spawn location for reading.")
	end
end)
