Why is my script not creating any SpawnLocations?

What I want: I want to create 6 separate Spawn Locations with different positions on my Baseplate. I want them to be invisible, and I want their CanCollide to be false.

What I get: As soon as I run my game, I take a look at the workspace. What I see is one Spawn Location that disappears after about 2 seconds.

I checked my spelling, keywords, punctuation. I checked the output, has no errors. I don't know what's going on. Please help.

spawnlocation = Instance.new("SpawnLocation",workspace)


function createSpawnA1()
	spawnlocation.Transparency = 1
	spawnlocation.CanCollide = false
	spawnlocation.Position = Vector3.new(462,0.5,48)
end

function createSpawnA2()
	spawnlocation.Transparency = 1
	spawnlocation.CanCollide = false
	spawnlocation.Position = Vector3.new(462,0.5,28)
end

function createSpawnA3()
	spawnlocation.Transparency = 1
	spawnlocation.CanCollide = false
	spawnlocation.Position = Vector3.new(462,0.5,8)
end

function createSpawnB1()
	spawnlocation.Transparency = 1
	spawnlocation.CanCollide = false
	spawnlocation.Position = Vector3.new(-237,0.5,9)
end

function createSpawnB2()
	spawnlocation.Transparency = 1
	spawnlocation.CanCollide = false
	spawnlocation.Position = Vector3.new(-237,0.5,29)
end

function createSpawnB3()
	spawnlocation.Transparency = 1
	spawnlocation.CanCollide = false
	spawnlocation.Position = Vector3.new(-237,0.5,49)
end


createSpawnA1()
createSpawnA2()
createSpawnA3()
createSpawnB1()
createSpawnB2()
createSpawnB3()

--This works
function createSpawn()
	local spawnLocation = Instance.new("SpawnLocation")
	spawnLocation.CanCollide = false
	spawnLocation.Position = Vector3.new(-11, 0.5, -28)
	spawnLocation.Transparency = 1
	spawnLocation.Parent = workspace
end

createSpawn()

I'm not sure why it's disappearing after 2 seconds, however, this is because you are using the same SpawnLocation object in all the function calls.

To fix this, try instantiating the SpawnLocation within the function definition like so:

function createSpawnA1()
	local spawnlocation = Instance.new("SpawnLocation")
	spawnlocation.Transparency = 1
	spawnlocation.CanCollide = false
	spawnlocation.Position = Vector3.new(462,0.5,48)
	spawnlocation.Parent = workspace -- doing this so someone don't backsass me
end
