Why does this error? ( Advanced Vectoring )

wait(5) -- Character load for studio 'Play Solo'
local Brick = game.Workspace.TestPart
local Player = game.Players['Player']

while wait() do
print(Player.Character.Torso['Position']) -- This works
Brick.Position=Vector3.new(Player.Character.Torso['Position']):lerp(Player.Character.Torso.CFrame*CFrame.new(0,2.5,-9)*CFrame.Angles(math.rad(-10),0,0),0.1)
end

--The print returns my Torso's Position but the Part doesnt CFrame to my torso. WHY?!?!?!
