Problem with one loop in another one

Question

When I drag and move cursor, X scale position will be show below. And then I click “add data in array”, the data should be put into array. I can move cursor again to add the second , the third ….into array.
My problem is:
In block diagram, once loop2 is outside of loop 1, it works. But I really want loop2 is in loop1 regarding to the rest part of the program. However, we I move loop2 into loop1, when I move cursor, nothing happens.
Please help to make it work or you have different way to do this job.
Thank you very much

Hey, no need to make it so complicated.  Just add an indicator on the CursLoc.X wire in the  "0 To 5 MHz": Cursor Move  case.
To answer your questions:
1) The indicator does not react because you are still within the inner while loop.  It will not change until that loop completes. I.e. the stop button is pressed.
2) Similarly, the stop 2 button will press, but nothing will happen until the inner loop is done.
Generally, when I am using an event structure, I try to keep all the changing UI inputs and outputs in the same while loop with the event structure, if not in the event structure itself.  Local variables and property nodes can get the job done, but they are inefficient and can be difficult to debug.  As I am sure you are discovering
