Arguments of the SubVI not updating in the main VI

[shabi]

Hello... I am implementing a process in labVIEW using state machine approach controlled by enum . In my state machine i am using a state indicator. The state indicator is the argument in my VI. When i call this VI in another VI the state indicator doesn't show the different states of the SubVI....

The same problem is for some other state results that are used as an arguments of the SubVI. But they are not changing/updating in the main calling VI.

Any solution please?

Your descriptions is not clear. You need to show us your code.

It sounds like you have a basic misunderstanding of how dataflow works. Unless you are willing to go through a lot of gymnastics you can't read an intermediate result form the inside of a subVI, from the caller.
