I have 2 while loops running. When the Boolean <Optimum Vacuum> goes true, the while loop below starts counting up a soak time. There are conditions where <Optimum Vacuum> in the top while loop goes false. At that point, I want the lower while loop to go false and stop adding up the soak time. The <Optimum Vacuum> variable in the bottom while loop never changes state from true to false, as it changes state in the top while loop. How can I make that variable change state as needed? Thank you

@Big_Guy wrote: How can I make that variable change state as needed? It is not the variable change, but giving the code a chance to read the new value, which is currently deadlocked. It seems your problem is solved, so here are a few more tips: Try to make the code less ambiguous and label the button either "Start" or "Stop". Naming it "Start Stop" and having some loops "stop if true" and some "continue if true" can raise a lot of confusion. If you want it as "Start Stop" on the front panel, use the caption (or boolean text) instead. Your innermost loop spins millions of times per second, consuming 100% of a CPU core, draining your battery, heating your office, and starving all other processes running on the computer. I am sure there is a reasonable upper speed limit, so place a small wait. Hard to tell more about the other loops, because most of the code is hidden in other cases or truncated. Not sure why there is a toplevel case structure. That's typically an architectural issue (Are you using "run continously"?). A typical well written state machine has a while loop as toplevel structure. If you would use "high resolution relative seconds" instead of "tick count", you would not need to divide by 1000 and there is no need for blue wires. etc.

Thank you for your help. I took your suggestions and ran with them. It will need a little fine tuning but overall it is doing what I want it to. Thank you again.
