update global variable on front panel of another VI

[lvuser333]

I have a main VI that has the GUI for the operators that has several steps with multiple sub vi's. I want to display the status (where I am in the process) on the GUI. I am using global variables, and the status updates in the global variable front panel just fine, however it only outputs the last value to the operator GUI. I would like it to show the new status at each point in the code. I read something about action engines but I am not sure is that is the correct way. I attached some code just as an example of how I am doing it right now.

i would implement a state machine, in your case. and look into references to bring the info up to the main vi if need to....

Based on your example, a state machine would work well.  I don't like using References to update indicator values.  It causes thread swapping and is slow.  I much prefer to use User Events to send data to an Event Structure.  The event structure can then update the indicators based on the data in the event itself.
