The Camera isn't working?

local target = Workspace.Grass
local camera = Workspace.CurrentCamera
camera.CameraType = Enum.CameraType.Scriptable
camera.CameraSubject = target
local angle = 100
local i = 0


while wait() do
    camera.CoordinateFrame = CFrame.new(target.Position)
                            * CFrame.Angles(0, angle, 0)
                            * CFrame.new(0, 100, 200)
    angle = angle + math.rad(1)
    script.Parent.StartGui.ClassFrame.Buttons.PlayKnightButton.MouseButton1Down:connect(function(onClick)
    print("Works")
        camera.CameraType = Enum.CameraType.Custom
        game.Workspace.CurrentCamera.CameraSubject = game.Players.LocalPlayer.Character.Humanoid
    end)
end

I am trying to get it so when a player joins the camera rotates around the baseplate. That works, but I want when the PlayKnightButton is presseed it changes the camera to the normal positon. It checks the mouse and does print "Works" and it changes the cameratype to custom and the subject to humanoid, but the camera is on a wierd angle. Any ideas?
