My teleportation script is not cannot find a child within workspace inside a local script?

local Player  = game.Players.LocalPlayer
local Mouse = Player:GetMouse()
TP1 = "aaa"
TP2 = "aaa"

Mouse.Button1Down:Connect(function()
    if workspace:FindFirstChild(TP1) then
    print("hm")
        workspace[TP1]:Destroy()
        TP1.Position = Mouse.Hit.Position
    else
    TP1 = Instance.new("Part")
    TP1.BrickColor = BrickColor.new("Really red")
    TP1.Parent = workspace
    TP1.Position = Mouse.Hit.Position
    end
end)

Mouse.Button2Down:Connect(function()
    if workspace:FindFirstChild(TP2) then
        workspace[TP2]:Destroy()
        TP2.Position = Mouse.Hit.Position
    else
    TP2 = Instance.new("Part")
    TP2.BrickColor = BrickColor.new("Really blue")
    TP2.Parent = workspace
    TP2.Position = Mouse.Hit.Position
    end
end)

After workspace:FindFirstChild it does not print "hm" even though the part is in workspace. Help?
