Specify which variables a sub VI will return to calling VI

[prenaut41]

Hello.  I think this is probably a relatively simple question to answer, but I can't seem to figure it out on my own. 

I'm want to call a subVI from a main VI and have the subVI return the values for certain acquired data to the calling VI. 

How can I desgnate a signal wire or indicator as an output variable to be returned to the calling VI.  Along those lines, how can I designate something in the subVI as an input from the calling VI?

Thanks

It's all in how you wire the connector pane. See the very first lesson in LabVIEW 101.

Thanks, Dennis.  The magic term you gave me to point me in the right direction was "connector pane".  I searched that term on the NI website and found the information I needed.
