error handling

[Kumar]

how do I pass the error in a VI to another vi. Let say I have developed a two vis. One is a calling one and the other is the called one. How do I pass error from the called vi to the calling one?

Exactly as all another outputs of vi: by terminal connection. Create Error Out Indicator and select it as output of vi. So caller vi will get error from the calling vi.
