"Please give us a simple answer, so that we don't have to think, because if we think, we might find answers that don't fit the way we want the world to be."
This line reminds me of General Relativity and Quantum Mechanics when taken looking at Black Holes for the quantum perspective. The answers do not fit the way the World seems to work.
Sorry, I digress...
Going back to what is important. Thank You for your help. I tested your example and it would only show me the dreaded white (blank page). Not even the last echo shows up.
if ($opt == "add")
Now, independently of my approach, I would really appreciate if you could lead me to the way where your example would work for me. I think that solving the issue the way I did does not make the one that is not working go away. I'd like to have both options. So, if you are up to it, with some infinite patience, it would interesting to find out why the Header("Location: does not work for me.
Once again thank You and have a nice weekend.
