Hi all, I'm designing a UI for a program I wrote and trying to implement it with a state machine. The machine doesn't really work at all; it just transitions between states without seemingly doing the checks it should be doing. Before I added the wait (for debugging), it would work as expected, until I'd changed two values, then the whole thing would freeze. Also, no matter how I set the Window Appearance settings, the abort button has gone away when running this VI. This input should basically run the user inputs through a series of checks to make sure they're entering sensical data, before sending it out to the main VI. One problem I have is that range_min and range_max are interdependent with their checks: They must both be positive, and nonzero range_min must be less than range_max range_max - range_min must be greater than or equal to 40. It seems this interdependence is what causes the crash when removing the wait statement, but I can't be sure. I've attached a zip containing the VI so you might check it out. Let me know what you think.

User Input State Machine does not work as expected - unsure what to do

You could use the Value(Signaling) property for each control inside of the cluster. You can just write the current value (or a default value). This would queue up a Value Changed event for each of those controls, forcing the check to be done.

Also, why can't references be included in subVIs (from the Edit - create subvi menu)?

Where would the subVI know where that is a reference to? You have to pass the references into subVIs.
