Humanoid:MoveTo isn't following player?

    enemy = script.Parent.Parent.Parent.Parent.Parent.Parent -- Enemy
    hum = enemy.Humanoid -- Enemy Humanoid

    local function HealthFunc()

        script.Parent.Size = UDim2.new(0, hum.Health * 150/hum.MaxHealth, 0, 50) -- Scale Gui for the Bar
        script.Parent.Stat.Text = tostring(hum.Health).."/"..hum.MaxHealth -- Change the Text

        if hum.Health <= 0 then

            enemy:Destroy() -- Destroy Enemy if Health is 0 or less (If it's Dead)

        end

        if enemy.OV.Value ~= nil then
            hum:MoveTo(enemy.OV.Value.HumanoidRootPart.Position)
            hum.MoveToFinished:Wait()
            print(enemy.OV.Value.HumanoidRootPart.Position)
        end

    end

    HealthFunc() -- Reset GUI when Enemy Spawned

    hum.HealthChanged:Connect(HealthFunc) -- Trigger Function when Health of Enemy is       Changed

The script tries to follow the player based on an object value.

if humanoid.Parent:FindFirstChild("OV") == nil then
        local objVal = Instance.new("ObjectValue")
        objVal.Name = "OV"
        objVal.Parent = humanoid.Parent
        objVal.Value = Player.Character
    else
        humanoid.Parent:FindFirstChild("OV").Value = Player.Character
    end
    humanoid:TakeDamage(Damage)

The object value is placed like this in the sword script and the enemy takes the position from the value of the object value.

No errors, it just doesn't work.
