Why isn't this spawning?

wait(1)

chr = game.Players.LocalPlayer.Character or game.Players.LocalPlayer.CharacterAdded:wait()
float = Instance.new("Part",chr)
float.Anchored = true
float.CanCollide = false
float.Transparency = 1
float.Position = chr.Torso.Position + Vector3.new(0,10,0)
model = Instance.new("Model")
model.Parent = chr
circle = Instance.new("Part",model)
circle.Anchored = true
circle.CanCollide = false
circle.BrickColor = BrickColor.new(0,0,0)
circle.FormFactor = "Custom"
circle.Size = Vector3.new(.2,5,.2)
circle.Transparency = 1
circle.Rotation = Vector3.new(-90,0,0)
circleB = Instance.new("Part")
circleB.FormFactor = "Custom"
circleB.Size = Vector3.new(0.2, 5, 5)
circleB.Anchored = true
circleB.CanCollide = false
circleB.BrickColor = BrickColor.new(0,0,0)
circleB.Transparency = 0
circleB.Shape = "Cylinder"


model.PrimaryPart = model.Part

for i = 1,180 do
    game:GetService('RunService').RenderStepped:wait()
    float.Position = chr.Torso.Position + Vector3.new(0,10,0)
    model:SetPrimaryPartCFrame(float.CFrame)
    clone = circle:Clone()
    clone.Parent = model
    clone.Transparency = 0
    clone.Position = float.Position
    clone.Rotation = Vector3.new(0,0,i)
    clone.Name = ("A"..i)
end
wait()

model.PrimaryPart = model.A1
float.CFrame = model.A1.CFrame
model:Destroy()
circleB.Parent = chr
circleB.CFrame = float.CFrame

for i = 0,3,.5 do
    game:GetService('RunService').RenderStepped:wait()
    circleB.Transparency = i
end



n=0
x = 0

while game:GetService('RunService').RenderStepped:wait() do
    n = n + 1
    x = x + 1
    float.Position = chr.Torso.Position + Vector3.new(0,10,0)
    if n == 360 then
        n = 0
    elseif x == 360 then
        x = 0
    end
    float.Rotation = Vector3.new(n,x,0)
    circleB.CFrame = float.CFrame
end

There are no errors, I'm trying to make my other circle script less laggy so I replaced my 180 parts with a mesh.
