OK, you clearly haven't understood LabVIEW's Principle of Data Flow. Let me introduce you to a Very Valuable Tool for LabVIEW Development -- the Pencil and Piece of Paper. Here's what you need to do: Write down what you want to do, in the broadest possible terms, not worrying about "how" (or "loops" or "Case Statements"). It clearly involves creating some Delimited Spreadsheets in LabVIEW 2013 (hmm). So give the names of the Spreadsheets, what they are supposed to contain, and how the data are created (you can say something like "Create pairs of random numbers to be arranged in rows until <some condition to stop, or a specific number of rows, it's up to you>"). If something happens next, when does it start, and what is it.
Your description in the previous post says "Spreadsheet section to cycle ever(y?) second" and "PID section to run (at?) real time". I'm not sure what you mean by that, so this is what you have to explain. Are you running two processes simultaneously? [This turns out to be something that LabVIEW does very easily, because of Data Flow -- if you explain what you want, we can probably show you how to do it]. One thing with parallel processes is to understand when they start (simultaneously?) and when they end (they don't need to end at the same time, but the program can't end until both simultaneous processes end).
