Michael, That's the ticket! It makes perfect sense - get a reference to the panel of the target VI, get an array of references to the controls on that panel, get the label of each control, find the reference to the desired control by searching for the matching label, then you have a reference to the target control and can create a property node that uses the value(signaling) property. It makes sense, but it seems far from obvious - however did you figure out this chain of calls would ultimately result in the control reference you were seeking? I never cease to be amazed by what the developers on this list can do!
Thanks again for the help!

Mark, Check ou this method of using value changed signaling event. Let me know if this is what you are doing: http://forums.lavausergroup.org/index.php?showtopic=139&view=findpost&p= 307 If you read through the post you will find other methods. Thank You Michael Aivaliotis
