title: Top value for generated picturebox isn't correctly adding
body: <p>I'm using this code: </p>
  
  <pre class="lang-vb prettyprint-override"><code>For Each srvr In discord.Guilds
  
    Dim top As Integer = 30
    Dim pb As New PictureBox
    pb.Width = 70
    pb.Height = 70
    pb.Left = 10
  
    pb.Top = top
    top = +30
    pb.Cursor = Cursors.Hand
  
    Dim ttImage As Bitmap = Bitmap.FromStream(New MemoryStream(tClient.DownloadData(srvr.IconUrl)))
    pb.BackgroundImage = ttImage
    pb.Tag = srvr.Id.ToString + " | " + srvr.Name
    pb.BackgroundImageLayout = ImageLayout.Zoom
    Me.Controls.Add(pb)
    pb.BringToFront()
  
  Next
  </code></pre>
  
  <p>The problem is, I have no clue why the top value doesn't place the Pictureboxes lower. I've tried doing <code>top += 30</code> as well, not working at all. How can I make this work?</p>
