Question about stacked sequence structure

Hi,
 
I made a numeric control outside a stacked sequence structure, and connect the control both to frame 1 and frame 2. In frame 2 there is a while loop structure. And now I start the labview program with the control A. Then, after frame 1 finished, frame 2 started, now I want to change the control to B and deliver B into frame 2. But the indicator in frame 2 shows that the control is still A. So I wonder how can I change the control and deliver it to the frame after the frame has started? Thank you!

NI Software :  LabVIEW  version 7.1
OS :  Windows XP

Dataflow dictates what you are seeing. The control does not get read once the sequence starts. This is as expected.

Some possible solutions:

  1. Just don't use stacked sequence! I don't and never feel limited by this choice. 😄
  2. Create local variable of the control and read from it inside frame 2.

Do you REALLY need a stacked sequence? Why??? 😮
