  • Thank you, it seems to work, even though I have no idea how. If you could add some comments so it would be easier for me to understand it line by line. If you don't want to do that, or don't have the time I understand, I will debug the code line by line and try to understand it. Again Thank you. Commented May 30, 2019 at 19:06
  • @Pangu: No worries. I get confused with this method all the time, too. It's fairly simple once you "see it". I will add some comments. Commented May 30, 2019 at 19:23
